embedded documents

Hello everybody,

I had a requirement to store complicated json documents in solr.

i have modified the JsonLoader to accept complicated json documents with
arrays/objects as values.

It stores the object/array and then flatten it and  indexes the fields.

e.g  basic example document

  {
        "titles_json":{"FR":"This is the FR title" , "EN":"This is the EN
title"} ,
        "id": 1000003,
        "guid": "3b2f2998-85ac-4a4e-8867-beb551c0b3c6"
   }

It will store titles_json:{"FR":"This is the FR title" , "EN":"This is the
EN title"}
and then index fields

titles.FR:"This is the FR title"
titles.EN:"This is the EN title"

Do you see any problems with this approach?

Regards,
Michael Pitsounis

Dynamically loaded core.properties file

Hi all, I have a question about dynamically loading a core properties 
file with the new core discovery method of defining cores.  The concept 
is that I can have a dev.properties file and a prod.properties file, and 
specify which one to load with -Dsolr.env=dev.  This way I can have one 
file which specifies a bunch of runtime properties like external servers 
a plugin might use, etc.

Previously I was able to do this in solr.xml because it can do system 
property substitution when defining which properties file to use for a core.

Now I'm not sure how to do this with core discovery, since the core is 
discovered based on this file, and now the file needs to contain things 
that are specific to that core, like name, which previously were defined 
in the xml definition.

Is there a way I can plugin some code that gets run before any schema or 
solrconfigs are parsed?  That way I could write a property loader that 
adds properties from ${solr.env}.properties to the JVM system properties.

Thanks!
Ryan

Inconsistent Solr Index Behavior

A while back we added a span support for multi-value fields and did a full
re-index for data spanning over 4 years.  It worked perfectly for a month,
and then suddenly results are not reliable anymore.  We are noticing that
the span is not working on most of the data and is returning wrong results.
 Is there anything that might corrupt or drop index data(old data)? Less
RAM? Something?

Question on Solr Relevancy using Okapi BM25F

I am trying to get OkapiBM25F working over some press release articles I am
indexing. The data has text portions spread across 3 fields - Title, Summary
and Full Article. 

 I would like to influence the standard BM25 by giving more weight to words
in title and summary of the article than the full description. The
importance has to be of the order title > Summary > Full description.

I am unable to find schema examples online that can help me with it. 

Can someone guide me with a possible schema for this. (or a link to an
article/blog that explains it)

Thanks for your help.

-Ritesh

Index not respecting Omit Norms

Please reference the below images:

<http://lucene.472066.n3.nabble.com/file/n4153863/Schema.png> 

<http://lucene.472066.n3.nabble.com/file/n4153863/SolrDescriptionSchemaBrowser.png> 

<http://lucene.472066.n3.nabble.com/file/n4153863/SolrDescriptionDebugResults.png> 

As you can see from the first image, the text field-type doesn't define the
omitNorms flag, meaning it is set to false. Also on the first image you can
see that the description field doesn't define the omitNorms flag, again
meaning it is set to false. (Default for omitNorms is false). This can all
be confirmed on the second image, where the Properties and Schema rows have
omitNorms set to checked.
I am having some issues understanding why some results have a fieldNorm set
to 1 for matches on the description field. As you can see from the third
image, the description field has a rather large number of terms in it, yet
the fieldNorm is being set to 1.0 for matching 'supply' on the description
field. My guess is that the Omit Norms flag for the 'Index' row is causing
the issue.
Questions:

From the first picture, can anyone tell me what each row (Properties, Schema
and Index) refers to? I think the Properties row refers to the flags set
when defining the Field Type, which for this field is text. The Schema row
refers to the flags set when defining the field, which is description. I'm
not as sure where the Index row flags come from, but I'm assuming it defines
what the index is really representing?  
Am I right in assuming the Omit Norms flag in the Index row of the first
picture is what is causing fieldNorm issues in the second image?

Performance of Boolean query with hundreds of OR clauses.

I am using Solr to perform search for finding similar pictures. 

For this purpose, every image indexed as a set of descriptors ( descriptor
is a string of 6 chars ) .
Number of descriptors for every image may vary ( from few to many thousands)

When I want to search  for a similar image , I am extracting the descriptors
from it and create a query like :
MyImage:( desc1 desc2 ...  desc n )

Number of descriptors in query may also vary. Usual it is about 1000.

Of course performance of this query very bad and may take few minutes to
return . 

Any ideas for performance improvement ? 

P.s I also tried to use lire , but it is not fits my use case.
