Determine if Merge is triggered in SOLR

[abhi Abhishek]

Hi All,
is there a way in SOLR to determine if a merge has been triggered in
SOLR? is there a API exposed to query this?

if its not available is there a way to do the same using lucene jar files
available in the SOLR libs?

Appreciate your help.

Best Regards,
Abhishek

SOLR Upgrade 3.x to 4.10

[abhi Abhishek]

Hi All,
I have SOLR 3.6 running currently, i am planning to upgrade this to
SOLR 4.10. Below were the thoughts we could come up with.

1. in place upgrade
   I would be making the SOLR 4.10 slave of 3.6 and copy the indexes,
and optimize this index.

  will optimizing the Lucene 3.3 index on SOLR 4 instance(with Lucene
4.10) change the index structure to Lucene 4.10? if not what would be the
version?
  if i enable docvalues on certain fields before issuing optimize, will
it be able to incorporate ( create .dvd & .dvm files ) that in the newly
created index?


2. Re-Index the data

Seeking advice for minimum time to upgrade this with most features of SOLR
4.10

Thanks in Advance

Best Regards,
Abhishek

Re: SOLR Upgrade 3.x to 4.10

[abhi Abhishek]

Thanks Erick and Shawn for the input. it makes more sense to move to SOLR
5.x but we would like to get there in few iterations gradually making
incremental changes to have a smooth cut over.

our index size is 3TB (10 shards of 300G each), i was looking for a
alternate route which would save me from pain of re-indexing. any thoughts
for the same would help.

Best Regards,
Abhishek

working of Sharded Query in SOLR 3.6

[abhi Abhishek]

Hi,
   I have a question about the distributed Querying in solr (
https://wiki.apache.org/solr/DistributedSearch),

let us consider the below call being made to solr server.

https://server1:8080/solr/core1/select?shards=server1:8080/solr/core1,server2:8070
/solr/core2,server3:8090/solr/core3&q=*:*&rows=10*&start=0

please correct if my understanding of the query processing here is
incorrect!

server1 acts as the master server for this request, and would spawn
requests toserver1, server2 and server3 for the given query and would wait
for the response from all the requests to return the response back to
client.

if this is the case(server1 waits on all the sharded calls to respond) how
would it join all the results from all the sharded calls?

if this is not how it does the processing can you please help me in
understanding the same.

Thanks in advance.

Thanks and Best Regards,
Abhishek Das

SOLR Backup and Restore - Solr 3.6.1

[abhi Abhishek]

Hello,
   we have solr 3.6.1 in our environment. we are trying to analyse
backup and recovery solutions for the same. is there a way to compress the
backup taken?

we have explored about replicationHandler with backup command. but as our
index is in 100's of GB's we would like a solution that provides
compression to reduce storage overhead.

thanks in advance

ZFS File System for SOLR 3.6 and SOLR 4

Re: SOLR Index in shared/Network folder

[abhi Abhishek]

Hello,
 Thanks for the suggestions. My aim is to reduce the disk space usage.
I have 1 master with 2 slave configured, where slaves are used for
searching and master ingests new data replicated to slaves, but as my index
size is in 100's of GB we see 3x times space overhead. i would like to
reduce this overhead, can you suggest something for this?

Thanks in Advance

Errors during Indexing in SOLR 4.6

Hi All,
 we recently migrated from SOLR 3.6 to SOLR 4, while indexing in SOLR 4
we are getting below exception.

Apr 1, 2015 9:22:57 AM org.apache.solr.common.SolrException log

this works perfectly fine in SOLR 3.6. can someone help in debugging this.
any fixes/solutions?

Re: [EXTERNAL] Re: Does anybody crawl to a database and then index from the database to Solr?

[abhi Abhishek]

Clayton

you could also try running and optimize on the SOLR index as a
weekly/bi weekly maintenance task to keep the segment count in check and
the maxdoc , numdoc count as close as possible (in DB terms de-fragmenting
the solr indexes)

Proximity Search using edismax parser.

[abhi Abhishek]

Hi All,
  How does proximity Query work in SOLR.

Example if i am running a query like below, for the field containing the
text “India registered a historical test match win against the arch rival
Pakistan here in Lords, England on Sunday”

Query: “Test match India Pakistan” ~ 10

I am interested in understanding the intermediate steps
involved here to understand the search behavior and determine how results
are being matched to the search phrase.

Thanks in Advance,

Abhishek

Re: Proximity Search using edismax parser.

[abhi Abhishek]

Thanks for the suggestions Erik and Vrindavda,

i was trying to understand how does the above query work when we have slop
set to 10. the debug output of the SOLR Query gave the terms which were
being looked up but the transpositions done to look up the search wasn't
exposed.

i found following stack overflow link which describes the transpositions
done when one is looking for phrase with slop 4. is there a guide to
understand this?

https://stackoverflow.com/questions/25558195/lucene-proximity-search-for-phrase-with-more-than-two-words

Thanks in advance.

Abhishek

Hi Everyone,

I have hit a weird behavior of Boolean Query, when I am

you please help me understand the behavior here?

 èReturns 0 matches

filter_queries: ((-documentTypeId:3) AND companyId:29096)

q=*:*&fq=(-documentTypeId:3+AND+companyId:29096)&version=2.2&start=0&rows=10&indent=on&debugQuery=true

è returns 1600 matches

Can you please help me understand what am I missing here?


Thanks in Advance.

explaination of query processing in SOLR

[abhi Abhishek]

Hello,
I am fairly new to SOLR, can someone please help me understand how a
query is processed in SOLR, i.e, what i want to understand is from the time
it hits solr what files it refers to process the query, i.e, order in which
.tvx, .tvd files and others are accessed. basically i would like to
understand the code path of the search functionality also significance of
various files in the solr directory such as .tvx, .tcd, .frq, etc.

Abhishek Das

Re: explaination of query processing in SOLR

Thanks Alex and Jack for the direction, actually what i was trying to
understand was how various files had an effect on the search.

Re: Error:Missing Required Fields for Atomic Updates

Update Handler expect all the required fields to be passed in even for the

Re: Reg:- Create Solr Core Using Command Line

[abhi Abhishek]

Hello,
I followed the steps outlined in your mail. i was able to get a running
core up fine. only thing I can think of in your case is the config
directory having all the required files for the SOLR Core to get
initialized. can you check if you have all the SOLR config files in the
config directory ( i.e, schema.xml, solrconfig.xml, also various supporting
files referred in the schema.xml) you specified on the command line?

can you share the conf directory, if you can?

Cheers!

Re: Reg:- Create Solr Core Using Command Line

[abhi Abhishek]

you can try using the post Tool.

bin/post -c film example/books_data.csv

SOLR 7.x stable version

[abhi Abhishek]

Hi All -
 I am using SOLR Cloud v6.5.0 and looking to upgrade it to SOLR 7.x;
any suggestions which are the most stable version in SOLR 7.x series.
from my initial reading, I see until SOLR 7.2 we had issues with CDCR
updates.

Thank you for your suggestions.

Thanks,
Abhishek
