Thanks Jack for your reply..
The problem is, I'm finding results for fq=title:(,10) but not for
fq=title:(, 10) - apologies if that was not clear from my first mail.
I have already mentioned the debug analysis in my previous mail.
Additionally, the title field is defined as below:
<fieldType name="text_wc" class="solr.TextField" positionIncrementGap="100"
>
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"
splitOnNumerics="0" preserveOriginal="1" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"
splitOnNumerics="0" preserveOriginal="1" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
I have the set catenate options to 1 for all types.
I can understand if ',' getting ignored when it is on its own (title:(,
10)) but
- Why solr is not searching for 10 in that case just like it did when the
query was (title:(,10))?
- And why other filter queries did not show up (collection:assets) in debug
section?
Thanks,
Sandeep
