which I have use as router field . I have try by make changes on

Hi Ketan,

I just want to be sure about your understanding of the 'implicit' router.

Implicit router in Solr puts the onus of correctly routing the documents on the 
user, instead of 'implicitly' or automatically routing them.

I don’t know of any such recommendation. Assuming you are not RAM or disk 
limited, going to two or three shards won’t help a lot. If those get you out of 
a bottleneck, you’ll see a difference.

I believe that some of the performance of Solr is proportional to the number of 
distinct terms in the index (the vocabulary). A rule of thumb is the vocabulary 
is proportional to the square root of the number of terms in the index. Which 
is often related to the number of documents. With this assumption, four shards 
gives a 2X speedup. Which has worked for me.

Number of shards - Best practice

Hi
I was recently told that ideally the number of shards in a SOLR cluster should 
be equal to a power of 2. If this is indeed a best practice, then what is the 
rationale behind this recommendation? ThanksImad

Hi, thanks for the feedback.

Yes, it is about OOM, indeed even solr instance makes unavailable. As I was 
saying I can't find more relevant information on logs.

We're are able to increment JVM amout, so, the first thing we'll do will be 
that.

As far as I know, all documents are bounded to that amount (14K), just the 
processing could change. We are making some tests on indexing and it seems it 
works without concurrent threads. Also we will try to decouple tika to solr.

By the way, make it available with solr cloud will improve performance? Or 
there will be no perceptible improvement?

Re: edismax parsing confusion

[Greg Pendlebury]

Try declaring your mm as 1 then and see if that assumption is correct.
Default 'mm' values are complicated to describe and depend on a variety of
factors. Generally if you want it to be a certain value, just declare it.

Problems creating index for suggestions

[Alexis Aravena Silva]

Hi,


I'm creating an index for suggestions, when I rebuild the index with 8 
documents, Solr creates a temp file that consumes over 20GB in the process and 
It takes more than 10 minutes in reindex, what is the problem?, It's illogic 
that Solr takes so long and consumes such size of my disk:



Filed Type Definition:



  




  
  

 

  



Suggester Configuration:




  fuzzySuggester
  FuzzyLookupFactory
  fuzzy_suggestions
  DocumentDictionaryFactory
  _sugerencia_
  idTipoRegistro
  text_suggestion
  false
  true


  infixSuggester
  AnalyzingInfixLookupFactory
  infix_suggestions
  DocumentDictionaryFactory
  _sugerencia_
  idTipoRegistro
  text_suggestion
  false
  true

  
  

  true
  infixSuggester
  fuzzySuggester
  true
  10
  true


  suggest

  



I rebuild the suggestions once by week, that's why I set buildOnCommit = true.


Regards.

Re: Fq and termfrequency are not showing the correct results

[Erick Erickson]

Functions like termfreq operate on single terms post analysis

Since it's an analyzed field you have no _term_ "bachelor's degree" or
even "bachelor degree" in the field. You have two terms, "bachelor"
and "degree". This also assumes that by "zero results" you mean you
get no frequency information back.

Erick

Hi,
I created a toy learning-to-rank model in solr in order to show the issues.

Feature.json

"class" : "org.apache.solr.ltr.feature.OriginalScoreFeature",
"params" : {}
  }
]

  "params" : {
  "weights": {

   "rankScore": 0.98
  }
   }
}

I could upload both feature and model  and performed re-ranking based
on the above model.   The issue was that when I stopped the solr
server and restarted it.
I got error message when I ran the same query to extract the features:

Any insights into the above strange behavior?

Problem with multi-valued field using Solr CEL

[Charlie Hubbard]

So I'm trying to index documents using Solr CEL and Tika on Solr 5.4.1.
I'm using the default configuration, but when I import my docs I'm getting
this error:

Here is my solrconfig.xml of the extract module:


  
true
ignored_


true
links
ignored_
  


I thought this would basically mark everything that wasn't a field as
ignored so meta shouldn't be imported.  I've searched through my solr
schema, and I have no meta field declared hence I thought CEL would throw
it out.

I'm using Solrj to import the docs.  I'm also adding a lot of literals to
the document.  You can see above the data that I'm providing in literals.

Why am I seeing this error?

Can I simply have it only extract the information and I'll put it in a text
field and have it process the HTML in the same manner to work around this
issue?

TIA
Charlie

Re: Phrase Fields performance

[David Hastings]

FYI, think i managed to get the results back and the speeds that i desired
back reducing the number of fields in the qf/pf values from 6 to 4, also
making sure to not boost the default field, and reducing the boost values
to much smaller numbers but still significant enough to boost properly, so
went from around .3 seconds pre qf/pf, above 1 sec after agressive
settings, and now back down to around half a second with modified values,
which I can live with.   also if anyone else like myself stores qtimes in a
table this is a good 15 minute rolling average sql query you may or may not
find useful:


SELECT when_done as timestamp, AVG( qtime ), count(id)  FROM qtimes WHERE
 `when_done` >=  '2017-03-23 09:00:00' AND `when_done` <=  '2017-03-23
13:00:00' GROUP BY year(when_done),month(when_done),day(when_done),( 4 *
HOUR( when_done ) + FLOOR( MINUTE( when_done ) / 15 ))  ORDER BY
 `qtimes`.`when_done` ASC;





pre qf/pf values:

Re: How to Apply 'implicit' routing in exist collection in solr 6.1.0

[Anshum Gupta]

Hi Ketan,

I just want to be sure about your understanding of the 'implicit' router.

Implicit router in Solr puts the onus of correctly routing the documents on
the user, instead of 'implicitly' or automatically routing them.

Re: Using function queries for faceting

[Mikhail Khludnev]

Exclude users' products, calculate default price facet, then facet only
user's products (in a main query) and sum facet counts. It's probably can
be done with switching domains in json facets.

Re: Using function queries for faceting

[Georg Sorst]

Hi Mikhail,

copying the default field was my first attempt as well - however, the
system in total has over 50.000 users which may have an individual price on
every product (even though they usually don't). Still, with the copying
approach this results in every document having 50.000 price fields. Solr
completely chokes trying to import this data.

Best,
Georg

You haven't described your index(es).  How many collections in the
cloud?  How many shards for each?  How many replicas for each shard? 
How many docs in each collection?  How much *total* index data is on
each of those systems?  To determine this, add up the size of the solr
home in all of the Solr instances that exist on that server.  With this
information, we can make an educated guess about whether the setup you
have engineered is reasonably correct for the scale of your data.

It sounds like you have twelve Solr instances per server, with each one
using a 31GB heap.  That's 372GB of memory JUST for Solr heaps.  Unless
you're dealing with terabytes of index data and hundreds of millions (or
billions) of documents, I cannot imagine needing that many Solr
instances per server or that much heap memory.

Have you increased the maximum number of processes that the user which
is running Solr can have?  12 instances of Solr is going to be a LOT of
threads, and on most operating systems, each thread counts against the
user process limit.  Some operating systems might have a separate
configuration for thread limits, but I do know that Linux does not, and
counts them as processes.

Side issue: It's generally preferable to only use either maxDoc or
maxTime, and maxTime will usually result in more predictable behavior,
so I recommend removing the maxDoc settings on autoCommit and
autoSoftCommit.  I doubt this will have any effect on the problem you're
experiencing, just something I noticed.  I recommend a maxTime of 6
(one minute) for autoCommit, with openSearcher set to false, and a
maxTime of at least 12 (two minutes) for autoSoftCommit.  If these
seem excessively high to you, go with 3 and 6.

On zkClientTimeout, unless you have increased the ZK server tickTime,
you'll find that you can't actually define a zkClientTimeout that high. 
The maximum is 20*tickTime.  A typical tickTime value is 2000, which
means that the usual maximum value for zkClientTimeout is 40 seconds. 
The error you've reported doesn't look related to zkClientTimeout, so
increasing that beyond 30 seconds is probably unnecessary.  The default
values for Zookeeper server tuning have been worked on by the ZK
developers for years.  I wouldn't mess with tickTime without a REALLY
good reason.

Another side issue: Putting Zookeeper data on a mechanical disk when
there are SSDs available seems like a mistake to me.  Zookeeper is even
more sensitive to disk performance than Solr is.

> Caused by: java.net.SocketTimeoutException: Read timed out

This error says that a TCP connection (http on port 9132) from one Solr
server to another hit the socket timeout -- there was no activity on the
connection for whatever the timeout is set to.  Usually a problem like
this has two causes:

1) A *serious* performance issue with Solr resulting in an incredibly
long processing time.  Most performance issues are memory-related.
2) The socket timeout has been set to a very low value.

In a later message on the thread, you indicated that the configured
socket timeout is ten minutes.  This should be plenty, and makes me
think option number one above is what we are dealing with, and the
information I asked for in the first paragraph of this reply is required
for any deeper insight.

Are there other errors in the Solr logfile that you haven't included? 
It seems likely that this is not the only problem Solr has encountered.

Thanks,
Shawn

Try Increasing the number of connections your ZooKeeper allows to a very

Make a new collection.  Or delete the collection and build it again with
different settings.

Changing the router on a collection is possible if you manually edit the
information in zookeeper, but there is no API to change it, because once
it is set and documents are indexed, changing it would break what
already exists.

Solr 6.x leaking one SolrZkClient instance per second?

[Markus Jelsma]

Hi,

One of our nodes became berzerk after a restart, Solr went completely nuts! So 
i opened VisualVM to keep an eye on it and spotted a different problem that 
occurs in all our Solr 6.4.2 and 6.5.0 nodes.

It appears Solr is leaking one SolrZkClient instance per second via 
DistributedQueue$ChildWatcher. That one per second is quite accurate for all 
nodes, there are about the same amount of instances as there are seconds since 
Solr started. I know VisualVM's instance count includes 
objects-to-be-collected, the instance count does not drop after a forced garbed 
collection round.

It doesn't matter how many cores or collections the nodes carry or how heavy 
traffic is.

Is this a known issue? Ticket?

Thanks,
Markus

Implementing DIH - Using a non-datetime change tracking column to Identify delta

[subinalex]

Hi Experts,

Can we use a non-datetime column to identify delta rows in deltaQuery for
DIH configuration.
Like for example in the below deltaQuery ,

  deltaQuery="select ID from category where last_modified 
'${dih.last_index_time}'"


the delta rows are picked when the last_modified datetime is greater than
last index time.

I want to pick the deltas if a column value differs from the corresponding
column value in solr.

 deltaQuery="select ID from category where md5hashcode  <> ;
'indexedmd5hashcode'"



Can we implement this?.

Hello Georg,
You can probably use {!frange} and  and a few facet.query enumerating price
ranges, but probably it's easier to just copy default price across all

Getting counts for JSON facet percentiles

[Georg Sorst]

Hi list!

Is it possible to get counts for the JSON facet percentiles? Of course I
could trivially calculate them myself, they are percentiles after all, but
there are cases where these may be off by one such as calculating the 50th
percentile / median over 3 results.

Thanks and best,
Georg

Re: Do streaming expressions support range facets?

[Joel Bernstein]

The facet expression, which uses the json facet API, currently does not
support range facets. So currently you would have to use the json facet API
directly to do range facets. The facet expression will support range facets
in the near future though.

There is a ticket open which adds date functions which could be used as
part of a rollup expression (
https://issues.apache.org/jira/browse/SOLR-10303). A rollup expression is
the MapReduce aggregation approach.

Using function queries for faceting

[Georg Sorst]

Hi list!

My documents are eCommerce items. They may have a special price for a
certain group of users, but not for other groups of users; in that case the
default price should be used. So the documents look like something like
this:

item:
  id: 1
  price_default: 11.5
  price_group1: 11.2
item:
  id: 2
  price_default: 12.3
  price_group2: 12.5

Now when I want to fetch the documents and display the correct price for
group1 I can use 'fl=def(price_group1,price_default)'. Works like a charm!
It will return price_group1 for document 1 and price_default for document 2.

Is there a way to do this for faceting as well? I've unsuccessfully tried:

* facet.field=def(price_group1,price_default)
* facet.field=effective_price:def(price_group1,price_default)
* facet.field={!func}def(price_group1,price_default)
* facet.field={!func}effective_price:def(price_group1,price_default)
* json.facet={price:"def(price_group1,price_default)"}

I'm fine with either the "old" facet API or the JSON facets.Any ideas?

Thanks!

Fwd: Fq and termfrequency are not showing the correct results

[Ayush Gupta]

Hi Everyone,

I have a document that contains data like this "Bachelor's degree is easier
to get" in the 'body' field and I am making a query on this field searching
for word 'Bachelor's degree' like this - query?fq=body:"bachelor%27s%
20degree"=body_frequency:termfreq(body,"bachelor%27s%20degree"),body and
I am getting zero results in response even when I have documents that
contains words like 'Bachelor's degree'.

I checked in the admin panel tab , there i can see the
WordDelimiterFilterFactory applied on the word 'Bachelor's Degree' and
converting it to 'Bachelor degree'. So both in the Field Value (Query) and
Field Value (Index) the WordDelimiterFilterFactory is converting the word
'Bachelor's Degree' to 'Bachelor's Degree' , SO why I am getting zero
results when quering. I have attached the screenshots of my analysis page.


I have attached a code file 'code.txt' where you can see the code for the
field 'body'.


Please tell me what Am I doing wrong.

Thanks

Re: Solr Cloud 6.5.0 Replicas go down while indexing

[Salih Sen]

Hi,

Sorry for the initial hurried up mail, here is some correction and further
explanation:

Problem I described previously was happening before we set zkClientTimeout
value so it was 3 when it happened.

autoCommit maxTime value is 15000 and autoSoftCommit maxTime is 6.

We recently removed maxDocs values from autoCommit settings and it seems
more stable so far and has better response time.

I can’t seem to find these values on Solr logs probably because logging
level is currently WARN but we left those as default so I think they’re set
as the values in solr.xml
${distribUpdateSoTimeout:60}
${distribUpdateConnTimeout:6}


We have 12 replicas using default routing. All commits and queries are
going to a single node because of the dummy client we use. Documents are
send in JSON format. I don’t have exact knowledge of document size, they
are mostly news article sized, though with lots of dynamic fields.

Sematext SPM currently shows “Added Docs Rate” as ~1.70k/sec for the server
that is receiving updates.

Once problem starts happening multiple replicas go down (not necessarily
the one receiving the update request from client) and cluster starts
returning errors to update requests.


We saw entries like following in Zookeeper logs that’s why we thought it
might be related to zkClientTimeout and value.

bq: We set Auto hardcommit time to 15sec and 1 docs, and soft

Just a sanity check, the commit intervals are in milliseconds, your
units look mixed up above, I'm guessing it's just a typo though. I
usually don't use maxDocs because it's unpredictable. Say you're
indexing at a furious rate. If you are indexing at 5,000 docs a second
(and assuming the above was supposed to be soft committing every 60
seconds or 5,000 docs) you'll still be autocommitting every second.

While that could be related, it's not particularly germane to your
timeout. My guess is that you're getting these errors on the leader?
what do you have in solr.xml for:

distribUpdateConnTimeout and distribUpdateSoTimeout

Those are likely the timeouts that matter. And how big are your
documents? The scenario I'm thinking of is that the leader sends the
update to the replica and the timeout for the replica's response
exceeds the ones above.

BTW, it can be useful on startup to look at your solr.log. The
_actual_ values for all the timeouts are printed out, including any
sysvars you've used.

And how are you indexing? Mostly I'm wondering how fast you're sending
docs to each leader and how.

Best,
Erick

Re: How to Insert and retrieve data from specific shard in Solr 6.1.0

[Erick Erickson]

Why? By it's nature, SolrCloud usually doesn't care about what shard a
document came from. Unless you use "implicit" routing, even _you_
don't know what shard the doc landed on.

But if you insist, address the request to a particular _replica_ that
happens to belong to the shard and add =false to the request.

Your request looks like
http://server:port/solr/collection/collection1_shard1_replica1?q=whatever=false.

Best,
Erick

Re: Problem starting solr 6.5

Hi,

I think you should check the permission of 
/usr/local/solr-6/solr-6.5.0/server/log

(maybe, you do not have write permission on the directory)

Tesseract prolly knows nothing of the EML format. Your scripts could pull EML's

Using Tesseract OCR to extract PDF files in EML file attachment

[Zheng Lin Edwin Yeo]

Hi,

Currently, I am able to extract scanned PDF images and index them to Solr
using Tesseract OCR, although the speed is very slow.

However, for EML files with PDF attachments that consist of scanned images,
the Tesseract OCR is not able to extract the text from those PDF
attachments.

Can we use the same method for EML files? Or what are the suggestions that
we can do to extract those attachments?

I'm using Solr 6.5.0

Edwin
