Re: Poll: Master-Slave or SolrCloud?

[Erick Erickson]

Otis:

bq: But it doesn't really matter so much whether people are the same or not

I'm going to gently disagree here. I regularly see questions on the
user's list about upgrading from 4.x or 3.x (!). So if the sample of
users responding to your poll are substantially the same users as
responded in 2013, there's no guarantee that they've even upgraded
Solr, much less thought it worthwhile to change their paradigm.

I suppose an interesting bit of additional data would be "when did you
start using Solr?". Would there be a greater percentage of responders
using SolrCloud in 2014 .vs. 2013? 2015 .vs. 2014? and so on.

Mind you I have zero data to support any of this, it's speculation and
I haven't looked at the poll so maybe I'm off base

Re: Poll: Master-Slave or SolrCloud?

[Otis Gospodnetić]

Hi,

I think it's roughly the same profile of people.  The poll from 2013 was on
Sematext blog and the new one is on Sematext Twitter account.  But it
doesn't really matter so much whether people are the same or not.  What
amazes me that in 2017 we don't see a lot more SolrCloud users!

Re: Troubleshooting solr errors

[Rick Leir]

Daniel,
Would it be too much trouble to get some text out of that particular email 
message, and try it in the Solr Admin Analysis tool? 

By the way, I also have my email in Dovecot. Would you be able to describe how 
you index it and how you query to find an email? Perhaps with scripts in a 
github project?
Thanks -- Rick

Yeah, this is kind of counter to my expectations too. I guess my
question is whether the same people are responding to the new survey
as the old one. "If it ain't broke" and all that.

Re: SOLR Indexed object delete automatically.

[Erick Erickson]

Are you using Data Import Handler (DIH?)? The "clean" option there
removes all the docs before running.

If not, then _someone_ is sending that command, Solr isn't generating
it by itself.

Erick

Re: How to add extra server to Cloud instance?

[Erick Erickson]

Just point the new Solr instance at the same Zookeeper ensemble, it'll
be added automatically.

However, you say: "..add one more server to this cloud to have extra
documents indexed and better performance"

What kind of "performance" are we talking here? If you want to add
another _shard_ because you have too many docs for adequate
performance even under light load, you'll have to either define a new
collection or use the SPLITSHARD command.

If you have adequate performance under light load but want to serve
more queries, then just ADDREPLICA.

Erick

How to add extra server to Cloud instance?

[Nilesh Kamani]

Hello All,

I created solr cloud instance and collection on Google cloud (Windows
Instance).
I used below command.

*solr create_collection -c booleansearch -shards 1 -replicationFactor 1*


I would like to add one more server to this cloud to have extra documents
indexed and better performance.
Could you please suggest me the steps I need to perform ?

Thanks,
Nilesh Kamani

Troubleshooting solr errors

[Daniel Miller]

I'm running Solr 6.4.2 to index my mail server (Dovecot). Searching is 
great - but periodically I have Solr errors. Previously, when an error 
would occur Solr would terminate.  I now have it running as a systemd 
service so it would auto-restart - but it seems like that doesn't solve it.


Some of the log lines include:

2017-04-24 18:18:31.101 ERROR (qtp594427726-30) [   x:dovecot] 
o.a.s.h.RequestHandlerBase org.apache.solr.common.SolrException: 
Exception writing document id 
17697/7db132200dd2df4d2f7b3bc41c5f/dmil...@amfes.com to the index; 
possible analysis error.


2017-04-24 18:18:31.125 ERROR (qtp594427726-32) [   x:dovecot] 
o.a.s.h.RequestHandlerBase org.apache.solr.common.SolrException: Error 
opening new searcher


I don't know what else to provide to try to troubleshoot this.

Re: SOLR Indexed object delete automatically.

[Erick Erickson]

Solr does not delete files/documents by itself with the exception of
TTL (Time To Live, since Solr 4.8. See:
https://lucidworks.com/2014/05/07/document-expiration/).

so unless you've configured TTL, which I doubt you have if you're
asking this question then I'd suspect several possibilities:

Multiple tables data aggregation

[solr2020]

Hi,

We have set of mongodb collections which has one-many mapping/relation. So
we are trying to create single document in solr from rows of different
mongodb collections at the time of indexing. Can anyone suggest the best
approach to achieve this?

Thanks.

Re: Using multi valued field in solr cloud Graph Traversal Query

[mganeshs]

Hi Joel,

Any idea from when multi value field is supported for gatherNodes ? I am
using version 6.5 ? Is it already there ? 

Kindly update,
Ganesh

Re: Solr SQL Subquery Support

The docs describe the supported features. So if it's not listed in the docs
it's not yet supported. The goal is to gradually increase SQL support.

Re: Numbers in the spellchecker: Mutations based on Levenshtein distance possible?

[alessandro.benedetti]

I would start with your spellchecker config and field analysis.
Then we can try to help you!

A shot in the dark is some kind of token filter such the word delimiter
which generates token that you are not expecting in the index ( if you are
using the Direct Spellcheck).
You can use your analysis tool in the admin dashboard or the schema browser
to take a look on what is happening.

Cheers

SOLR Indexed object delete automatically.

[Saurav Maulick]

Hi Team,

We are using Solr 5.4.1 (in Windows with Zookeper). Our problem is Solr
automatically delete all indexed files.from last couple of days.

Is their any Maxout setting which can cause this issue?

This is our production issue and any quick help is highly appreciated.

Numbers in the spellchecker: Mutations based on Levenshtein distance possible?

[Christian Ortner]

Hello everyone,

I'm working on a query correction feature based on collations generated by
the spellchecker. This works like a charm, except when numeric tokens are
present in the query. In that case, I don't get any corrections for the
number, although corrections for textual tokens are still made.

Any ideas?

Best regards,

Re: Modify solr score

[tstusr]

We came with a simple solution.

We use  termfreq    and
write a simple processor that counts words for making a boost function that
only calculates the ratio between words that hit terms and the whole field
length.

Some tests are being made, maybe it could solves the problem.

Thanks for your help!

Poll: Master-Slave or SolrCloud?

[Otis Gospodnetić]

Hi,

I'm really really surprised here.  Back in 2013 we did a poll to see how
people were running Master-Slave (4.x back then) and SolrCloud was a bit
more popular than Master-Slave:
https://sematext.com/blog/2013/02/25/poll-solr-cloud-or-not/

Here is a fresh new poll with pretty much the same question - How do you
run your Solr?  -
and guess what?  SolrCloud is *not* at all a lot more prevalent than
Master-Slave.

We definitely see a lot more SolrCloud used by Sematext Solr
consulting/support customers, so I'm a bit surprised by the results of this
poll so far.

Is anyone else surprised by this?  See https://twitter.com/sematext/
status/854927627748036608

Thanks,
Otis

Re: Mixing AND OR conditions with query parameters

[Erick Erickson]

Michael's comments are spot on, and the deeper thing you should be
aware of is that Solr query parsing does not implement strict boolean
logic, see Chris Hostetter's excellent blog here:
https://lucidworks.com/2011/12/28/why-not-and-or-and-not/

As Michael suggests, parenthesizing carefully can make the parsing
behave like boolean logic.

+1 to what Rick said.

Although Solr is a webapp, since version 5.0, the only supported
deployment option is the jetty that Solr comes with and the scripts
provided.

https://wiki.apache.org/solr/WhyNoWar

It is possible that in the last two years (since 5.0 was released) Solr
has become reliant on the code mechanisms provided by Jetty and certain
things will no longer function under Tomcat.

You could try the url without "index.html" and see whether it works ...
but you're running an unsupported configuration. To get help, you're
going to have to run it as it was shipped, not in Tomcat.

I tried the URL you mentioned on a Solr 6.5 download running with the
included scripts, and it worked ... but under Tomcat, we can't be sure
of anything.

Thanks,
Shawn

This kind of range works with DateRangeField, it does *not* work with
TrieDateField.  You're going to have to completely reindex after you
change the class on your fieldType and reload the collection or core.

I commented on that issue and closed it as Invalid.

If you are creating the HttpClient object external to the Solr client,
you cannot use SolrJ methods to set timeouts.  You must set the timeouts
on the HttpClient object before you give it to SolrJ.  The second code
example on SOLR-6542 has HttpClient code to do this, but then it
proceeds to also try and set the timeouts using SolrJ methods, which
isn't going to work.

If you are running into this exception when you are *not* creating
HttpClient yourself, that's a different problem ... but I can pretty
much guarantee that it won't be addressed in any 4.x or 5.x version. 
HttpSolrServer has been deprecated in the 5.x versions and is completely
gone in the 6.x versions.  It has been replaced by HttpSolrClient.

Thanks,
Shawn

RE: DistributedUpdateProcessorFactory was explicitly disabled from this updateRequestProcessorChain

[Pratik Thaker]

Hi Alessandro,

Can you please suggest what should be the correct order of adding processors ?

I am having 5 collections, 6 shards, replication factor 2, 3 nodes on 3 
separate VMs.

Pratik Thaker

Subject: RE: DistributedUpdateProcessorFactory was explicitly disabled from 
this updateRequestProcessorChain

Let's make a quick differentiation between PRE and POST processors in a Solr 
Cloud atchitecture :

 "In a single node, stand-alone Solr, each update is run through all the update 
processors in a chain exactly once. But the behavior of update request 
processors in SolrCloud deserves special consideration. " cit. wiki

*PRE PROCESSORS*
All the processors defined BEFORE the distributedUpdateProcessor happen ONLY on 
the first node that receive the update ( regardless if it is a leader or a 
replica ).

*POST PROCESSORS*
The distributedUpdateProcessor will forward the update request to the the 
correct leader ( or multiple leaders if the request involves more shards), the 
leader will then forward to the replicas.
The leaders and replicas at this point will execute all the update request 
processors defined AFTER the distributedUpdateProcessor.

" Pre-processors and Atomic Updates
Because DistributedUpdateProcessor is responsible for processing Atomic Updates 
into full documents on the leader node, this means that pre-processors which 
are executed only on the forwarding nodes can only operate on the partial 
document. If you have a processor which must process a full document then the 
only choice is to specify it as a post-processor."
wiki

In your example, your chain is definitely messed up, the order is important and 
you want your heavy processing to happen only on the first node.

For better info and clarification:

here a working alternative to your chain)

Re: Inconsistent Counts in Cloud at Solr SQL Queries

[Joel Bernstein]

SQL has two aggregation modes: facet and map_reduce. Facet uses the json
facet API directly so SOLR-7452 would apply if it hasn't been resolved yet.
map_reduce always gives accurate results regardless of the cardinality but
is slower. To increase performance using map_reduce you need to increase
the size of the cluster (workers, shards, replicas).

Make sure to have a whitespace are the OR operator.

The parenthesises should be around the OR query, not including the "fq:"

all).

Inconsistent Counts in Cloud at Solr SQL Queries

[Furkan KAMACI]

Hi,

As you know that json facet api returns inconsistent counts in cloud set up
(SOLR-7452). I would like to learn that is the situation same for Solr SQL
queries too?

Kind Regards,
Furkan KAMACI

Re: How to use Wordnet in solr?

[alessandro.benedetti]

No no Pablo, what I am saying is that you will need to :

1) download the wordnet file
2) upload it to Solr as a managed resource
3) use the synonym token filter with the wordnet format.

I don't know ( and I don't think it is possible right now) how to configure
a managed resource to fetch data from an online service, maybe could be a
good addition for this specific synonym filter.

Cheers

Re: prefix facet performance

[alessandro.benedetti]

Thanks Yonik and Maria.
It make sense, if we reduce the number of terms, term enum becomes a very
good solution.
@Yonik : do we still check the prefix on the term dictionary one by one, or
an FST is used to identify the set of candidate terms ?

I will check the code later,

Regards

 Hi,
  Through SolrJ I am trying to upload configsets and create
 collections in my solrcloud.

 Setup:
 1 Standalone zookeeper listening on 2181 port. version 3.4.10
 -- bin/zkServer.sh start
 3 Starting solr nodes. (All running from the same solr.home) version
 6.5.0 and as well in 6.2.1
 -- bin/solr -c -z localhost:2181 -p 8983
 -- bin/solr -c -z localhost:2181 -p 8984
 -- bin/solr -c -z localhost:2181 -p 8985

 After first run of my java application to upload the config and create
 the collections in solr through zookeeper is seemless and working
 fine.
 Here is the clusterstatus after the first run.
 https://gist.github.com/shadow-fox/5874f8b5de93fff0f5bcc8886be81d4d#file-3nodes-json

 Stopped one solr node via:
 -- bin/solr stop -p 8985
 clusterstatus changed to:
 https://gist.github.com/shadow-fox/5874f8b5de93fff0f5bcc8886be81d4d#file-3nodes1down-json

 Till now everything is as expected.

 Here is the remaining part where it confuses me.

 Bring the down node back to life. Clusterstatus changed from 2 node
 down with 1 node not found to 3 node down including the new node that
 just brought up.
 https://gist.github.com/shadow-fox/5874f8b5de93fff0f5bcc8886be81d4d#file-3nodes3down-json
 Expected result should be all the other nodes should be in active mode
 and this one would be recovery mode and then it would be active mode,
 as this node had data before i stopped it using the script.

 Now I added one more node to the cluster via
 -- bin/solr -c -z localhost:2181 -p 8986
 The clusterstatus changed to:
 https://gist.github.com/shadow-fox/5874f8b5de93fff0f5bcc8886be81d4d#file-4node3down-json
 This one just retains the previous state and adds the node to the cluster.


 When bringing up the removed node which was previously in the cluster
 which was registered to the zookeeper and has data about the
 collections be registered as active rather than making every other
 node down ? If so what is the solution to this ?

 When we add more nodes to an existing cluster, how to ensure that it
 also gets the same collections/data i.e. basically synchronizes with
 the other nodes which are present in the node rather than manually
 create collection for that specific node ? As you can see from the
 lastly added node's clusterstate it is there in the live_nodes but
 never got the collections into its data dir.
 Is there any other way to add a node with the existing cluster with
 the cluster data ?

 For the completion here is the code that is used to upload config and
 create collection through CloudSolrClient in Solrj.(Not full code but
 part of it where the operation is happening.)
 https://gist.github.com/shadow-fox/5874f8b5de93fff0f5bcc8886be81d4d#file-code-java
 Thats all there is for a collection to create: upload configsets to
 zookeeper, create collection and reload collection if required.

 This I have tried in my local Mac OS Sierra and also in AWS env which
 same effect.

[David]

Dear,manager:


   I have a problem with deploying the solr6.5. my environment are

The detail is "The origin server did not find a current representation for the 
target resource or is not willing to disclose that one exists." Could you tell 
me why it happened and how to solve this problem? Thank you!
