Return doc if one or more query keywords occur multiple times

[gistolero]

Hello,

I am using Dismax request handler for queries:

...select?q=foo bar foo2 bar2&qt=dismax&mm=2...

With parameter "mm=2" I configure that at least 2 of the optional clauses must 
match, regardless of how many clauses there are.

But now I want change this to the following:

List all documents that have at least 2 of the optional clauses OR that have at 
least one of the query terms (e.g. foo) more than once.

Is this possible?
Thanks,
Gisto

delta-import for XML files, Solr statistics

[gistolero]

Hello,

I have some questions about DataImportHandler and Solr statistics...


1.)
I'm using the DataImportHandler for creating my Lucene index from XML files:

###
$ cat data-config.xml 

 
  
   

  ...

###

No problems with this configuration - All works fine for full-imports, but...

===> What means 'rootEntity="false"' and 'dataSource="null"'?



2.)
The documentation from DataImportHandler describes the index update process for 
SQL databases only...

My scenario:
- My application creates, deletes and modifies files from /tmp/files every 
night.
- delta-import / DataImportHandler should "mirror" _all_ this changes to my 
lucene index (=> create, delete, update documents).

===> Is this possible with delta-import / DataImportHandler?
===> If not: Do you have any suggestions on how to do this?



3.)
My scenario:
- /tmp/files contains 682 'myDoc_.*\.xml' XML files. 
- Each XML file contains 12 XML elements (e.g. foo).
- DataImportHandler transfer only 5 from this 12 elements to the lucene index. 


I don't understand the output from 'solr/dataimport' (=> status):

###

 ...
 
  0
  1363
  0
  2008-10-24 13:19:03
  
Indexing completed. Added/Updated: 681 documents. Deleted 0 documents.
  
  2008-10-24 13:19:05
  2008-10-24 13:19:05
  0:0:2.648
  
...


===> What is "Total Rows Fetched" rsp. what is a "row" in a XML file? An 
element? Why 1363?
===> Why shows the "Added/Updated" counter 681 and not 682?



4.)
And my last questions about Solr statistics/informations...

===> Is it possible to get informations (number of indexed documents, stored 
values from documents etc.) from the current lucene index?
===> The admin webinterface shows 'numDocs' and 'maxDoc' in 'statistics/core'. 
Is 'numDocs' = number of indexed documents? What means 'maxDocs'?


Thanks a lot!

Ok so, at the moment I have to do a full-import to update my index. What 
happens with (user) queries while full-import is running? Does Solr block this 
queries the import is finished? Which configuration options control this 
behavior?

/tmp/files$ ls myDoc_*.xml | wc -l
682

But "Added/Updated" shows 681. Does this mean that one file has an XML error? 
But the statistic says "Total Documents Skipped" = 0?!

Do you have answers for this questions too?

Calculating peaks

[gistolero]

Hello,

How can I get ALL the matching documents back? How can I return an unlimited 
number of rows?
Yes, I have read the FAQ and I got your point, but I need Solr to calculate 
number based peaks for my indexed data:

- For each of my documents the text ('text'), the creation time ('date') and 
other fields are saved. But for this query I'm only using 'text' and 'date'!
- If the query string is found in 'text', Solr returns only the value from 
'date' (not from 'text').
- My application uses a map to store all returned dates and to count the 
frequency of occurrence.
- The application uses the map for calculating peaks.


Two questions:

===> Is it possible to return _all_ documents, if the query response contains 
only one small field ('date')?

===> Do you have an hints for tuning such a query? I am using the 'fl=date' 
parameter. Is there a better way?


Thanks a lot

Re: Calculating peaks - solrj support for facet.date?

[gistolero]

Sorry, but I have one more question. Does the java client solrj support 
facet.date?

QueryResponse knows the getFacetDates() method but I don't understand how to 
set facet.date, facet.date.start, facet.date.end, and facet.date.gap for the 
query. It seems that SolrQuery doesn't provide functions for this purpose.

It would be very nice if you could post some code examples.

Thanks again
Simon

full-import with solrj (solr Java client)

[gistolero]

Hello,

I want to run a (DataImportHandler) full-import with solrj. I understand how to 
send queries with SolrQuery etc., but I don't know how to construct the 
"dataimport?command=full-import&commit=true" path. Which classes do I have to 
use? SolrRequest? It would be very nice if you could post some code examples.

Thank you

Using properties from core configuration in data-config.xml

[gistolero]

Hello,

is it possible to use properties from core configuration in data-config.xml?
I want to define the "baseDir" for DataImportHandler.


I tried the following configuration:


*** solr.xml ***


  

 
  

...
  





*** data-config.xml ***


 
  
   
 



But this is the result:

...
Nov 17, 2008 1:50:08 PM org.apache.solr.handler.dataimport.DataImporter 
doFullImport
INFO: Starting Full Import
Nov 17, 2008 1:50:08 PM org.apache.solr.core.SolrCore execute

point to a directory Processing Document # 1
 at 
org.apache.solr.handler.dataimport.FileListEntityProcessor.init(FileListEntityProcessor.java:81)
...




I tried also to configure all dataimport settings in solrconfig.xml, but I 
don't know how to do this exactly. Among other things, I tried this format:


*** solrconfig.xml ***

...

 
  
   FileDataSource
   

 xmlFile
 FileListEntityProcessor
 ${xmlDataDir}
 id-.*\.xml
 false
 null"
 
   data
   id
   ${xmlFile.fileAbsolutePath}
 ...

...



But all my tests (with different "dataimport" formats in solrconfig.xml) failed:


...
INFO: Reusing parent classloader
Nov 17, 2008 2:18:14 PM org.apache.solr.common.SolrException log

Re: Using properties from core configuration in data-config.xml

[gistolero]

Very cool :-)

Both suggestions work fine! But only with solr version 1.4:
https://issues.apache.org/jira/browse/SOLR-823

Use a nightly build (e.g. 2008-11-17 works):
http://people.apache.org/builds/lucene/solr/nightly/

See below for examples for both solutions...

// *** solr.xml ***













// *** solrconfig.xml ***
  

  ./data-config.xml


  
${xmlDataDir}
  




// *** data-config.xml ***

  

  


URL for full-import:
http://localhost:8983/solr/core1/dataimport?command=full-import&commit=true

// *** data-config.xml ***

  

  


URL for full-import:
http://localhost:8983/solr/core1/dataimport?command=full-import&commit=true&xmlDataDir=%2Fhome%2Fcore1


Thats all.

Combine facet.date and facet.field

[gistolero]

Hello,

I'm using the facet.date function to get all matching docs per day:

q=foo&rows=0&facet=true&facet.date=date&facet.date.start=2009-01-31T00:00:00Z&facet.date.end=2009-03-01T23:59:59Z&facet.date.gap=+1DAY&fq=+size:big

2009-01-31T00:00:00Z -> 13 hits
2009-02-01T00:00:00Z -> 10 hits
...

As you see, the result is filtered by the "fq" parameter. The downside for this 
solution is that I have to run the query for every value from field "size" 
(big, small, ...). Is there an easier way to produce the following result with 
a single query only?

big -> 2009-01-31T00:00:00Z -> 13 hits
big -> 2009-02-01T00:00:00Z -> 10 hits
...
small -> 2009-01-31T00:00:00Z -> 1 hits
small -> 2009-02-01T00:00:00Z -> 7 hits
...

Thanks

DisMax query parser syntax for the fq parameter

[gistolero]

Hello,

I am using the dismax query parser syntax for the fq param:

.../select?qt=dismax&rows=30&q.alt=*:*&qf=content&fq={!dismax 
qf=contentKeyword^1.0 mm=0%}Foo&fq=+date:[2009-03-11T00:00:00Z TO 
2009-07-09T16:41:50Z]&fl=id,date,content


Now, I want to add one more field to the qf parameter:

...&fq={!dismax qf=titleKeyword^1.8 contentKeyword^1.0 mm=0%}Foo&...

=> Solr should return a doc, if "titleKeyword" OR "contentKeyword" contains 
"Foo".


But this results in an error:

SEVERE: org.apache.solr.common.SolrException: 
org.apache.lucene.queryParser.ParseException: Expected identifier
at pos 43 str='{!dismax qf=titleKeyword^1.8 contentKeyword^1.0 mm=0%}Foo'

Is it possible to use the fq filter for multiple fields?

Thanks
Gisto
