Subject Re: defType argument weirdness
Date Tue, 19 Jul 2011 17:25:27 GMT
qf_dismax and pf_dismax   are irrelevant -- I shouldn't have included  
that info.  They are passed in the url and they work;   they do not  
affect this problem.

Your reminder of debugQuery  was a good one - I use that a lot but  
forgot in this case.

Regardless, I thought that     defType=dismax&q=*:*   is supposed to  
be equivalent to  q={!defType=dismax}*:*  and also equivalent to q={! 
dismax}*:*


defType=dismax&q=*:*   DOESN'T WORK
<str name="rawquerystring">*:*</str>
<str name="querystring">*:*</str>
<str name="parsedquery">+() ()</str>
<str name="parsedquery_toString">+() ()</str>

leaving out the explicit query
defType=dismax     WORKS
<null name="rawquerystring"/>
<null name="querystring"/>
<str name="parsedquery">+MatchAllDocsQuery(*:*)</str>
<str name="parsedquery_toString">+*:*</str>


q={!dismax}*:*   DOESN'T WORK
<str name="rawquerystring">*:*</str>
<str name="querystring">*:*</str>
<str name="parsedquery">+() ()</str>
<str name="parsedquery_toString">+() ()</str>

leaving out the explicit query:
q={!dismax}    WORKS
<str name="rawquerystring">{!dismax}</str>
<str name="querystring">{!dismax}</str>
<str name="parsedquery">+MatchAllDocsQuery(*:*)</str>
<str name="parsedquery_toString">+*:*</str>


q={!defType=dismax}*:*    WORKS
<str name="rawquerystring">{!defType=dismax}*:*</str>
<str name="querystring">{!defType=dismax}*:*</str>
<str name="parsedquery">MatchAllDocsQuery(*:*)</str>
<str name="parsedquery_toString">*:*</str>

leaving out the explicit query:
q={!defType=dismax}    DOESN'T WORK
