Hi Jack,
Thanks for your response again and for helping me out to get through this.
The URL is definitely encoded for spaces and it looks like below. As I
mentioned in my previous mail, I can't add it to query parameter as that
searches on multiple fields.
The title field is defined as below:
<field name="title" type="text_wc" indexed="true" stored="false"
multiValued="true"/>
q=countryside&rows=20&qt=assdismax&fq=%28title%3A%28,10%29%29&fq=collection:assets
<requestHandler name="assdismax" class="solr.SearchHandler">
<lst name="defaults">
<str name="defType">edismax</str>
<str name="echoParams">explicit</str>
<float name="tie">0.01</float>
<str name="qf">title^10 description^5 annotations^3 notes^2 categories</str>
<str name="pf">title</str>
<int name="ps">0</int>
<str name="q.alt">*:*</str>
<str name="fl">*,score</str>
<str name="mm">100%</str>
<str name="q.op">AND</str>
<str name="sort">score desc</str>
<str name="facet">true</str>
<str name="facet.limit">-1</str>
<str name="facet.mincount">1</str>
<str name="facet.field">uniq_subtype_id</str>
<str name="facet.field">component_type</str>
<str name="facet.field">genre_type</str>
</lst>
<lst name="appends">
<str name="fq">collection:assets</str>
</lst>
</requestHandler>
The term 'countryside' needs to be searched against multiple fields
including titles, descriptions, annotations, categories, notes but the UI
also has a feature to limit results by providing a title field.
I can see that the filter queries are always parsed by LuceneQueryParser
however I'd expect it to generate the parsed_filter_queries debug output in
every situation.
I have tried it as the main query with both edismax and lucene defType and
it gives me correct output and correct results.
But, there is some problem when this is used as a filter query as the the
parser is not able to parse a comma with a space.
Thanks again Jack, please let me know in case you need more inputs from my
side.
Best Regards,
Sandeep
