fw: (Issue) How improve solr facet performance

[Alice.H.Yang (mis.cnsh04.Newegg) 41493]

Hi, Solr Developer

  Thanks very much for your timely reply.

1.  I'm sorry, I have made a mistake, the total number of documents is 32 
Million, not 320 Million.
2.  The system memory is large for solr index, OS total has 256G, I set the 
solr tomcat HEAPSIZE="-Xms25G -Xmx100G"

-How many fields are you faceting on?

Reply:  9 fields I facet on.

- How many unique values does your facet fields have (approximately)?

Reply:  3 facet fields have one hundred unique values, other 6 facet fields' 
unique values are between 3 to 15. 


- What is the content of your facets (Strings, numbers?)

Reply:  9 fields are all numbers.

- Which facet.method do you use?

Reply:  Used the default facet.method=fc

And we test this scenario:  If the number of facet fields' unique values is 
less we add facet.method=enum, there is a little to improve performance.

- What is the response time with faceting and a few thousand hits?

Reply: 
   QTime is  6

It is not clear whether your observation of increased response time is due to 
many hits or faceting in itself.

- How many fields are you faceting on?
- How many unique values does your facet fields have (approximately)?
- What is the content of your facets (Strings, numbers?)

That depends on whether your bottleneck is the hitcount itself, the number of 
unique facet values or something third like I/O.

SolrCloud Nodes autoSoftCommit and (temporary) missing documents

[Michael Tracey]

Hey all,

I've got a number of nodes (Solr 4.4 Cloud) that I'm balancing with HaProxy for 
queries.  I'm indexing pretty much constantly, and have autoCommit and 
autoSoftCommit on for Near Realtime Searching.  All works nicely, except that 
occasionally the auto-commit cycles are far enough off that one node will 
return a document that another node doesn't.  I don't want to have to add 
something like this: timestamp:[* TO NOW-30MINUTE] to every query to make sure 
that all the nodes have the record.  Ideas? autoSoftCommit more often?

 
   10 
   720 
   false

   5000
 

Thanks,

M.

Re: Import data from Mysql concat issues

[anarchos78]

Tomcat setup is fine. I insist that it's Solr's issue. The whole index
consists of Greek (funny characters) and solr returns them normally. The
problem here is that I cannot concatenate Greek characters in
"data-config.xml" (hard-coded).

Re: Import data from Mysql concat issues

[Erick Erickson]

bq: I think that it happens at index time

How do you know that? If you're looking at the results in a browser
you do _not_ know that. If you're looking at the raw values in, say,
SolrJ then you _might_ know that, there's still the issue of whether
you're sending the docs to Solr and your servlet container is munging
them. In this latter case, you're right the info is indexed that way.

Either way, it's not Solr's problem. Solr works just fine with utf-8.
So if the data is getting into the index with weird characters, it's
your setup. If it's just a browser problem, it's _still_ a problem
with your setup.

FWIW,
Erick

Re: Solr 4.7.2 ValueSourceParser classCast exception

[Jack Krupansky]

Are you sure that you compiled your code with the proper Solr jars so that 
the class signature (extends, implements, and constructors) matches the Solr 
4.7.2 jars? I mean, Java is simply complaining that your class is not a 
valid value source class of the specified type.

I think that it happens at index time. The reason is that when i query for

Re: Import data from Mysql concat issues

[Erick Erickson]

Couple of possibilities:

1> The data in Solr is fine. However, your browser is getting the
proper characters back but is not set up to handle the proper
character set so displays .

2> Your servlet container is not set up (either inbound or outbound)
to handle the character set you're sending it.

I must admit I do not fully understand it in detail, but it is a known problem 
with Field Cache (facet.method=fc) faceting. The remedy is to use DocValues, 
which does not have the same limitation. This should also result in lower heap 
usage. You will have to re-index everything though.

We have successfully used DocValues on an index with 400M documents and 300M 
unique values on a single facet field.

Internals about "Too many values for UnInvertedField faceting on field xxx"

[张月祥]

Could anybody tell us some internals about "Too many values for
UnInvertedField faceting on field xxx" ?

 

We have two solr servers.

 

Solr A :  

 

128G RAM, 60M docs, 2600 different terms with field “code”,  every term of
field “code” has fixed length 6.

the sum count of token of field “code” is 9 Billions. 

The total space used by field “code” is 50 Billions.

 

 

Solr B:  

 

128G RAM, 140M docs,1600 different terms with field “code” every term of
field “code” has fixed length 6.

the sum count of token of field “code” is 18 Billions

The total space of field “code” is 90 Billions.

 

 

When we do facet query “
q=*:*&wt=xml&indent=true&facet=true&facet.field=code”  

Solr B is OK,  BUT Solr A meets Exception with the message “Too many values
for UnInvertedField faceting on field code”.

 

Now we think the limitation of UnInvertedField is related with the number of
different terms with one field

 

Could anybody tell us some internals about this problem? We won’t to use
facet.method=enum because it ‘s too slow to use.

 

Thanks!

Re: How does query on AND work

[Per Steffensen]

I can answer some of this myself now that I have dived into it to 
understand what Solr/Lucene does and to see if it can be done better
* In current Solr/Lucene (or at least in 4.4) indices on both 
"no_dlng_doc_ind_sto" and "timestamp_dlng_doc_ind_sto" are used and the 
doc-id-sets found are intersected to get the final set of doc-ids
* It IS more efficient to just use the index for the 
"no_dlng_doc_ind_sto"-part of the request to get doc-ids that match that 
part and then fetch timestamp-doc-values for those doc-ids to filter out 
the docs that does not match the "timestamp_dlng_doc_ind_sto"-part of 
the query. I have made changes to our version of Solr (and Lucene) to do 
that and response-times go from about 10 secs to about 1 sec (of course 
dependent on whats in file-cache etc.) - in cases where 
"no_dlng_doc_ind_sto" hit about 500-1000 docs and 
"timestamp_dlng_doc_ind_sto" hit about 3-4 billion.

Hi

Lets say I have a Solr collection (running across several servers) 
containing 5 billion documents. A.o. each document have a value for 
field "no_dlng_doc_ind_sto" (a long) and field 
"timestamp_dlng_doc_ind_sto" (also a long). Both "no_dlng_doc_ind_sto" 
and "timestamp_dlng_doc_ind_sto" are doc-value, indexed and stored. 
Like this in schema.xml
stored="true" required="true" docValues="true"/>
positionIncrementGap="0" docValuesFormat="Disk"/>


I make queries like this: no_dlng_doc_ind_sto:() AND 
timestamp_dlng_doc_ind_sto:([ TO ])
* The "no_dlng_doc_ind_sto:()"-part of a typical query will hit 
between 500 and 1000 documents out of the total 5 billion
* The "timestamp_dlng_doc_ind_sto:([ TO ])"-part 
of a typical query will hit between 3-4 billion documents out of the 
total 5 billion


Question is how Solr/Lucene deals with such requests?
I am thinking that using the indices on both "no_dlng_doc_ind_sto" and 
"timestamp_dlng_doc_ind_sto" to get two sets of doc-ids and then make 
an intersection of those might not be the most efficient. You are 
making an intersection of two doc-id-sets of size 500-1000 and 3-4 
billion. It might be faster to just use the index for 
"no_dlng_doc_ind_sto" to get the doc-ids for the 500-1000 documents, 
then for each of those fetch their "timestamp_dlng_doc_ind_sto"-value 
(using doc-value) to filter out the ones among the 500-1000 that does 
not match the timestamp-part of the query.
But what does Solr/Lucene actually do? Is it Solr- or Lucene-code that 
make the decision on what to do? Can you somehow "hint" the 
search-engine that you want one or the other method used?


Solr 4.4 (and corresponding Lucene), BTW, if that makes a difference

Hello,

I looked to source code of post.jar, that was very interesting.
I looked for manifoldcf apache, that was interesting too.
But i what i want to do is indexing some files using http rest, this is my

Change the group.field name in the solr response

[Prathik Puthran]

Hi,

How can I change the field name in the "grouped" section of the solr
response.
I know for changing the field names in the response where solr returns
documents you can make a query with "fl" changed as
"fl=mapping1:fieldname1,mapping2:fieldname2"

How do I achieve the same thing for "grouping"?

For eg: If the solr returns the below response for "grouped" section when I
send the query with "group.field=fieldname"

"grouped": {"fieldname": {"matches": 1,"ngroups": 1,"groups": [{"groupValue
": "11254","doclist": {"numFound": 1,"start": 0,"docs": [{"store_id": 101,"
name": "tubelight ","fieldname": "14"}]}}]}},

I want solr to change the "fieldname" in the response to say some other
value I specify in the query.
How can I achieve this?

Thanks,
Prathik

Hey Anass,

Have look at another Apache project : http://manifoldcf.apache.org

It works with Tomcat/Solr. It is handy to handle deletions and incremental

Feel free to look at the source code for post.jar. I mean, all it is really

Fwd: Question to send

[rashi gandhi]

HI,



I have one running solr core with some data indexed on solr server.

This core  is designed to provide OpenNLP functionalities for indexing and
searching.

So I have kept following binary models at this location:
*\apache-tomcat-7.0.53\solr\collection1\conf\opennlp
*

· en-sent.bin

· en-token.bin

· en-pos-maxent.bin

· en-ner-person.bin

· en-ner-location.bin



*My Problem is*: When I unload the running core, and try to delete conf
directory from it.

It is not allowing me to delete directory with prompt that *en-sent.bin*and
*en-token.bin* is in use.

If I have unloaded core, then why it is not unlocking the connection with
core?

Is this a known issue with OpenNLP Binaries?

How can I release the connection between unloaded core and conf directory.
(Specially binary models)



Please provide me some pointers on this.

Thanks in Advance

Is there a particular reason you are adverse to using post.jar? I mean, if 
there is some bug or inconvenience, let us know so we can fix it!


The Solr server itself does not provide any ability to "crawl" file systems 
(LucidWorks Search does.) post.jar does provide that convenience.

Re: How to Disable Commit Option and Just Manage it via SolrConfig?

[Jack Krupansky]

There is no direct Solr configuration option to disable commit requests that 
I know of.


Maybe you could do it with an update processor. The ProcessAdd method is 
called to process a document; it is passed an AddUpdateCommand object for a 
single document and has a field for the commitWithin setting. I don't see a 
public method for zapping commitWithin, but I didn't look too deeply. Worst 
case, you would need to substitute your own equivalent of 
RunUpdateProcessorFactory that ignores the commitWithin setting on 
ProcessAdd; maybe you could subclass and extend the existing class, or maybe 
you would have to copy and edit it.


Also, note that the delete command also has a commitWithin setting.

Subject: How to Disable Commit Option and Just Manage it via SolrConfig?

Hi All;

I've designed a system that allows people to use a search service from
SolrCloud. However I think that I should disable "commit" option for people
to avoid performance issues (many users can send commit requests and this
may cause to performance issues). I'll configure solr config file with
autocommit and I'll not let people to commit individually.

I've done some implementation for it and people can not send commit request
by GET as like:

localhost:8983/solr/update*?commit=true*

and they can not use:

HttpSolrServer solrServer = new HttpSolrServer("http://localhost:8983/solr
");
solrServer*.commit();*

I think that there is another way to send a commit request to Solr. It is
something like:

{"add":{ "doc":{"id":"change.me","title":"change.me
"},"boost":1.0,"overwrite":true,"*commitWithin*":1000}}

So, I want to stop that usage and my current implementation does not
provide it.

My question is that: Is there anyway I can close the commit option for Solr
from "clients"/"outside the world of Solr" and manage that option only via
solr config?

Import data from Mysql concat issues

[anarchos78]

Hi,

I'm trying to index data from mysql. The indexing  is successful. Then I
tried to use the mysql concat function (data-config.xml) in order to
concatenate a custom string with a field like this: *CONCAT('(',
CAST('ΤΜΗΜΑ' AS CHAR CHARACTER SET utf8), ' ', apofasi_tmima, ')') *. The
custom string ('ΤΜΗΜΑ') in Greek. Then when I try to query the field solr
returns "?" instead of "ΤΜΗΜΑ". I have also use this: *CONCAT('(',
'ΤΜΗΜΑ', ' ', apofasi_tmima, ')')* with no success.
The "data-config.xml" file is utf-8 encoded and at the beginning there is
the "" xml directive. I have also
tried to set in the dataSource url “characterEncoding=utf8” but indexing
fails.
What am I missing here? Is there any workaround for this?
Below is a snippet from data-config.xml:

Re: How to Disable Commit Option and Just Manage it via SolrConfig?

[Furkan KAMACI]

Hi Michael;

I've written an API that users send their request. I resend their queries
into Solr and manage which collection is theirs and drop query parameters
about commit. However users can send commitWithin option within their
request data and I have to analyze the data inside request to disallow it.
That's why I'm looking a solution for it within Solr without customizing it.
