Solr 3.4 problem with words separated by coma without space

[elisabeth benoit]

Hello,

I'm using Solr 3.4, and I'm having a problem with a request returning
different results if I have or not a space after a coma.

The request "name, number rue taine paris" returns results with 4 words out
of 5 matching ("name", "number", "rue", "paris")

The request "name,number rue taine paris" (no space between coma and
"number") returns no results, unless I set mm=3, and then matching words
are "rue", "taine", "paris".

If I check in the solr.admin.analyzer, I get the same analysis for the two
different requests. But it seems, if fact, that the lacking space after
coma prevents name and number from matching.


My field type is


      <analyzer type="query">
        <!-- découpage standard -->
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <!-- normalisation des accents, cédilles, e dans l'o,... -->

      </analyzer>

Anyone has a clue?
