Solr returns different results for fq vs q

Question

I have movie data indexed already in Solr. The basic queries are working as expected but when I fire a filter query for facets along with aq, the result is different.

The query /select?q=facetGenre:Drama&wt=xml returns results

Whereas the query /select?q=*.*&fq=facetGenre:Drama&wt=xml does not return any result.

What could the reason for this ? please help.

Since there are "\\" in Genre field eg "Action\\Adventure", it is of a custom field type "facetStringwithSlash. The details as below

<fieldType name="facetStringwithSlash" class="solr.TextField" positionIncrementGap="100">

<analyzer type="index">
<tokenizer class="solr.PatternTokenizerFactory" pattern="[/,]\s*"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="0" generateNumberParts="0" catenateWords="0" preserveOriginal="1" catenateNumbers="0" catenateAll="0" splitOnCaseChange="0" stemEnglishPossessive="1"/>
<filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>

<analyzer type="query">

<filter class="solr.ASCIIFoldingFilterFactory"/></analyzer></fieldType>

As @joeln pointed out, you should use : in your query.

select?q=*:* would mean match any value in any field.

In case of select?q=*.* , since no field is specified in query, so it would search in default field, and match for any text that have . in it. Maybe that's the reason that you are not getting any hits in response.
