Hi Jeniba,

You can add fields and field types using Solrj with SchemaRequest.Update 
subclasses - see here for a list: 


There are quite a few examples of doing both in the tests:

Re: Index and query brackets

[Anil]

Thanks Chris for the response.

I am using TextField and edismax query parser.

i have changed filters so that brackets are not trimmed. i will test it and
let the group know if that is working.

Thanks.

Re: Index and query brackets

[Chris Hostetter]

If you index the literal string value of "[ DATA ]" and then you wnat to 
be able to query for "[ DATA ]" again later there are two things you have 
to consider:

1) how is your field value analyzed?

If you use something like StrField then an index term for the literal 
string "[ DATA ]" is created and put in your index, but if you use 
TextField then the analyzer configured might do things like tokenize the 
string into 3 distinct terms, lowercase alpha charagers, or perhaps even 
drop the bracket characters completely -- as long as that is consistent at 
index time and query time then you should be fine, as long as you pay 
attention to...

2) what query parser are you using.

The default parser treats brackets and whitespace as special meta-syntax 
characters.  You can quote them, or backslah escape them but the 
whitespace itself may also need to be quoted/escaped to prevent the parser 
from trying to make a boolena query for 3 terms ("[", "DATA", "]") instead 
of 1.

alternatively you can use things like the "field" QParser, which let's you 
target a specific field by name, with a query string value that can be 
anything -- there are no special meta-syntax characters for hte field 
parser. and the appopriate analyer wll be used to create a TermQuery or 
PhraseQuery (as needed)

ie: q = {!field f=your_field_name}[ DATA ]

Re: Problem using bbox in schema

[Chris Hostetter]

can you please send us the entire schema.xml file you were using when you 
got that error?

Would be nice to get to the bottom of how/why you gut an error regarding 
"positionIncrementGap" on AbstractSpatialPrefixTreeFieldType.

ApacheCon: Getting the word out internally

[Melissa Warnkin]

ApacheCon: Getting the word out internally
Dear Apache Enthusiast,

As you are no doubt already aware, we will be holding ApacheCon in
Seville, Spain, the week of November 14th, 2016. The call for papers
(CFP) for this event is now open, and will remain open until
September 9th.

The event is divided into two parts, each with its own CFP. The first
part of the event, called Apache Big Data, focuses on Big Data
projects and related technologies.

Website: http://events.linuxfoundation.org/events/apache-big-data-europe
CFP:
http://events.linuxfoundation.org/events/apache-big-data-europe/program/cfp

The second part, called ApacheCon Europe, focuses on the Apache
Software Foundation as a whole, covering all projects, community
issues, governance, and so on.

Website: http://events.linuxfoundation.org/events/apachecon-europe
CFP: http://events.linuxfoundation.org/events/apachecon-europe/program/cfp

ApacheCon is the official conference of the Apache Software
Foundation, and is the best place to meet members of your project and
other ASF projects, and strengthen your project's community.

If your organization is interested in sponsoring ApacheCon, contact Rich Bowen
at e...@apache.org  ApacheCon is a great place to find the brightest
developers in the world, and experts on a huge range of technologies.

I hope to see you in Seville!

Re: Cold replication

[Mahmoud Almokadem]

Thanks Erick,

I'll take a look at the replication on Solr. But I don't know if it well
support incremental backup or not.

And I want to use SSD because my index cannot be held in memory. The index
is about 200GB on each instance and the RAM is 61GB and the update
frequency is high. So, I want to use SSDs equipped with the servers instead
on EBSs.

Would you explain what you mean with proper warming?

Thanks,
Mahmoud

Re: Indexing using SolrOutputFormat class

[Erick Erickson]

You're looking at a class that is specific to the
MapReduceIndexerTool which uses EmbeddedSolrServer
to build sub-indexes. These sub-indexes are then
merged via the tool into indexes suitable for
copying to (or merging with) existing Solr indexes
on a shard-by-shard basis.

If you're using MapReduce to process the files
and trying to index them to a live Solr cluster,
just use the regular SolrJ CloudSolrClient,
assemble lists of SolrInputDocuments and send
them to Solr with CloudSolrClient.add(doclist).

I usually use batches of 1,000 for small documents.

MRIT is intended for initial bulk loading. Last I knew,
for instance, it does not replace documents with the
same document ID () since it relies on
merging the index using Lucene's merge capability
which does not check for duplicate doc IDs.

Best,
Erick

Re: Problem using bbox in schema

Those work fine for me (latest 6x version). It looks to me like
you've changed some _other_ field, this error

Can't set positionIncrementGap on custom analyzer class

looks like you have some text-related field you've also changed
and likely have a custom analyzer somewhere?

Re: index sql databases

[Erick Erickson]

I don't see how that relates to the original
question.

bq: when I display the field type date I get the
value in this forme -MM-dd'T'hh:mm:ss'Z'

A regex in the _input_ side will have
no effect on what Solr returns. You'd have
to use a DocTransformer to change the output
on the query side. DIH is in the indexing side.

Best,
Erick

Re: Cold replication

[Erick Erickson]

Have you tried the replication API backup command here?
https://cwiki.apache.org/confluence/display/solr/Index+Replication#IndexReplication-HTTPAPICommandsfortheReplicationHandler

Warning, I haven't worked with this personally in this
situation so test.

I do have to ask why you think SSDs are required here and
if you've measured. With proper warming, most of the
index is held in memory anyway and the source of
the data (SSD or spinning) is not a huge issue. SSDs
certainly are better/faster, but have you measured whether
they are _enough_ faster to be worth the added
complexity?

Re: SolrCloud - Query performance degrades with multiple servers(Shards)

[Erick Erickson]

+1 to Susheel's question. Sharding inevitably adds
overhead. Roughly each shard is queried
for its top N docs (10 if, say, rows=10). The
doc ID and sort criteria (score by default) are returned
to the node that originally got the request. That node
then sorts the lists into the real top 10 to return to
the user. Then the node handling the request re-queries
the shards for the contents of those docs.

Sharding is a way to handle very large data sets, the
general recommendation is to shard _only_ when you
have too many documents to get good query perf
from a single shard.

If you need to increase QPS, add _replicas_ not shards.
Only go to sharding when you have too many documents
fit on your hardware.

Best,
Erick

Re: How to Add New Fields and Fields Types Programmatically Using Solrj

Hi Jeniba,

You can add fields and field types using Solrj with SchemaRequest.Update 
subclasses - see here for a list: 


There are quite a few examples of doing both in the tests:

DateMath parsing change?

[Timothy Potter]

I have code that uses the DateMathParser and this used to work in 5.x
but is no longer accepted in 6.x:

time:[NOW-2DAY TO 2016-07-19Z]

org.apache.solr.common.SolrException: Invalid Date in Date Math
String:'2016-07-19Z'
at org.apache.solr.util.DateMathParser.parseMath(DateMathParser.java:241)

This is in a unit test, so I can change it, but seems like regression to me?

Re: JDBC: Collection not found with count(*) and uppercase name

[Joel Bernstein]

This looks a like a bug with SQL stats query which uses the StatsStream.
The table name should be case insensitive.

The simple select query is using CloudSolrStream which is properly handling
the table name.

Feel free to create a jira for this.

Cold replication

[Mahmoud Almokadem]

Hi, 

We have SolrCloud 6.0 installed on 4 i2.2xlarge instances with 4 shards. We 
store the indices on EBS attached to these instances. Fortunately these 
instances are equipped with TEMPORARY SSDs. We need to the store the indices on 
the SSDs but they are not safe.

The index is updated every five minutes. 

Could we use the SSDs to store the indices and create an incremental backup or 
cold replication on the EBS? So we use EBS only for storing indices not serving 
the data to the solr.

Incase of losing the data on SSDs we can restore a backup from the EBS. Is it 
possible?

Thanks, 
Mahmoud

BooleanQuery Migration from Solr 4 to SOlr 6

[Max Bridgewater]

HI Folks,

I am tasked with migrating a Solr app from Solr 4 to Solr 6. This solr app
is in essence a bunch of solr components/handlers. One part that challenges
me is BooleanQuery immutability in Solr 6.

Here is the challenge: In our old code base, we had classes that
implemented custom interfaces and extended BooleanQuery. These custom
interfaces were essentially markers that told our various components where
the user came from. Based on the user's origin, different pieces of logic
would apply.

Now, in Solr 6, our custom boolean query  can no longer extend BooleanQuery
since BooleanQuery only has a private constructor. I am looking for a clean
solution to this problem.

Here are some ideas I had:

1) Remove the logic that depends on the custom boolean query => Big risk to
our search logic
2) Simply remove BooleanQuery as super class of custom boolean query =>
Major risk. Wherever we do “if(query instanceof BooleanQuery) “, we would
not catch our custom queries.
3) Remove BooleanQuery as parent to the custom query (e.g. make it extend
Query) AND Refactor to move all “if(query instanceof BooleanQuery) “ into a
dedicated method: isCustomBooleanQuery. This would return “query instanceof
BooleanQuery || “query instanceof CustomQuery“. We then need to change ALL
20 occurrences of this test and ensure we handle both cases appropriately.
==> Very invasive.
4) Add a method createCustomQuery() that would return a boolean query
wherein a special clause is added that allows us to identify our custom
queries.  This special clause should not impact search results. => Pretty
ugly.


Other potential clean, low risk, and less invasive solution?

Indexing using SolrOutputFormat class

[rashi gandhi]

Hi All,



I am using Solr-5.0.0 API for indexing data in our application and the
requirement is to index the data in batches, using solr-mapreduce API.



In our application, we may receive data from any type of input source for
example: file, streams and any other relational or non-relational Db’s in a
particular format. And I need to index this data into Solr, by using
SolrOutputFormat class.



As per my analysis until now, I find that SolrOutputFormat works with the
EmbeddedSolrServer and requires path to config files for indexing data,
without the need of passing host and port for creating the SolrClient.



I checked for the documentation online, but couldn’t find any proper
examples that make the use of SolrOutputFormat class.

Does anybody have some implementations or a document, which mentions
details like what exactly needs to be passed as input to SolrOutputFormat
configuration, etc.?



Any pointers would be helpful.

Re: Find part of long query in shorter fields

[CA]

Hi Ahmet,


thank you for the link. It helped me to find more resources.

What I still don’t understand, though, is why the edismax returns one of the 
documents with a partial hit and not the other:


q=Braun Series 9 9095CC Men's Electric Shaver Wet/Dry with Clean and Renew 
Charger
// edismax with qf/pf : „name“ and „brand“ field

HIT:
name: "Braun Series Clean CCR2 Cleansing Dock Cartridges Lemonfresh 
Formula Cartrige (Compatible with Series 7,5,3) 2 pc“
brand: Braun

NOT A HIT:
name: "Braun 9095cc Series 9 Electric Shaver“
brand: Braun

(explainOther, schema, solrconfig for this, see my previous e-mail)


I’m still thinking that if I could understand what is happening then it would 
help me figure out what the solution for my use case is. Maybe edismax would be 
perfectly fine with the right combination of fieldtypes and config values?


Thanks for your input!
