Question

I am a novice with Solr and i was trying the example that comes in the example folder of Solr(3.6) package(apache-solr-3.6.0.tgz). I started the server and posted the sample xml files in example/exampledocs and then i could search for stuff and Solr would return matches and it was all good. But then i tried posting another xml file with more than 10,000 documents. I modified the example/solr/conf/schema.xml file to add the fields of my xml file and then restarted the server and posted my xml file. I checked the statistics in Solr admin panel(http://localhost:8983/solr/admin/stats.jsp) and it shows numDocs : 10020. Now this means that the documents were successfully posted. But when i search for anything that was present in my posted documents(from the 10,000 document xml file),it returns 0 results. But Solr is still able to return results from searches that match content in the documents that come by default in the example/exampledocs folder. I am clueless about what has happened here. The value of numDoc clearly suggests that the documents i posted in the xml file were indexed.
Anything else i can inspect to see what’s wrong with this?

The schema which comes in the example with the Solr package is like this

<field name="id" type="string" indexed="true" stored="true" required="true"/>
<field name="sku" type="text_en_splitting_tight" indexed="true" stored="true" omitNorms="true"/>
<field name="name" type="text_general" indexed="true" stored="true"/><field name="alphaNameSort" type="alphaOnlySort" indexed="true" stored="false"/>
<field name="manu" type="text_general" indexed="true" stored="true" omitNorms="true"/>
<field name="cat" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="features" type="text_en_splitting" indexed="true" stored="true" multiValued="true"/>
<field name="includes" type="text_general" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true"/>
<field name="weight" type="float" indexed="true" stored="true"/>
<field name="price" type="float" indexed="true" stored="true"/>
<field name="popularity" type="int" indexed="true" stored="true"/>
<field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="subject" type="text_general" indexed="true" stored="true"/>
<field name="description" type="text_general" indexed="true" stored="true"/>
<field name="inStock" type="boolean" indexed="true" stored="true"/>

and more….

The schema of the xml file which i posted had some fields in common with the above schema like title,description,price,etc so i entered the rest of the fields in schema.xml like this

<field name="cid" type="int" indexed="false" stored="false"/>
<field name="discount" type="float" indexed="true" stored="true"/>
<field name="link" type="string" indexed="true" stored="true"/>
<field name="status" type="string" indexed="true" stored="true"/>
<field name="pubDate" type="string" indexed="true" stored="true"/>
<field name="image" type="string" indexed="false" stored="false"/>

If you are using the default settings from the Solr example site, then by virtue of the df setting in the solrconfig.xml file for the /select request handler, it is setting the default search field to the text field.

<requestHandler name="/select" class="solr.SearchHandler">
   <!-- default values for query parameters can be specified, these
        will be overridden by parameters in the request
    -->
   <lst name="defaults">
     <str name="echoParams">explicit</str>
     <int name="rows">10</int>
     <str name="df">text</str>
   </lst>
  ....
 </requestHandler>

If you look in the schema.xml file just below the field definitions you will see the multiple copyField settings that are moving the values from certain fields into the text field and therefore making them searchable via the default field setting. In your example of searching for Sony in the title field, if you look at the copyField statements, you will see that the title field is not being copied to the text default search field. Therefore, the documents with the Sony title value are not being returned in your query.

I would suggest the following:

1. Try a query by specifying the following: title:Sony that should return what you are expecting.
2. If you want the title field to be included in the default query field, then add the following copyField statement to the schema.xml file and reload your 10000 document file.
   <copyField source="title" dest="text">

I hope this helps.
