How can I boost bq in FieldQParserPlugin?
Hi, ALL.
My original query is:
http://myhost:8080/solr/select?q=ipod&*bq=userId:12345^0.5*
&fq=&start=0&rows=10&fl=*%2Cscore&qt=dismax&wt=standard&debugQuery=on&explainOther=&hl.fl=
It works this way.
But I would like to place bq phrase in the default solrconfig.xml
configuration to make the query string more brief, so I did the following?
http://myhost:8080/solr/select?q=ipod&*bq={!field f=userId v=$qq}&qq=12345*
&fq=&start=0&rows=10&fl=*%2Cscore&qt=dismax&wt=standard&debugQuery=on&explainOther=&hl.fl=
However, filedQueryParser doesn't accespt a boost parameter, then what shall
I do?
Thanks in advance.

...hmmm, i'm not sure why that's happening, but it certianly seems like a
bug -- i ust have no idea what that bug is.
the inner dismax parser should definitely be producing a query where the
DisjunctionMaxQuery for "12345" is "mandatory" but that mandatory clause
should be wrapped inside of another boolean query which should be added to
the outermost query as an "optional" clause.
somewhere that BooleanQuery produced by the inner dismax parser is getting
thrown away ... hmmm, actually that this is a neccessary behavior of
DismaxQParser for some cases (that it sheds it's own outermost
BooleanQuery when not needed), but in this case it's screwing you because
it doesn't realize you really do need it.
does this owrk better? ...
q=ipod&bq={!dismax qf=userId^0.5 v=$qq bq=*:*^0}&qq=12345&qt=dismax&debugQuery=on
...it's kind of kludgy, but it should garuntee you that wrapping
BooleanQuerry is preserved.

Although infinite recursion is disappeared, there is another problem.
q=ipod&bq={!dismax qf=userId^0.5 v=$qq bq=}&qq=12345&qt=dismax&debugQuery=on
I try to debug the above query, it turned out to be as:
+DisjunctionMaxQuery((content:ipod | title:ipod^4.0)~0.01) ()
+DisjunctionMaxQuery((userId:12345^0.5)~0.01)
see, the second(embeded) DisMax is marked as *Mandatory*, thus the purpose
of boosting the main query cannot be achieved.
Apparently, this is not it's expected to be.
Any ideas?

That is a problem... if bq is a dismax, and part of dismax is the bq
param, you do get infinite recursion.
One way around it is to define any args that could cause infinite
recursion in the embedded dismax query (namely the bq param).
So try
q=ipod&bq={!dismax qf=userId^0.5 v=$qq bq=}&qq=12345&qt=dismax
Note: I just added an empty bq param to the nested dismax query.

Is it problematic when I use dismax as additional boost query with bq params
of upper level dismax query?
My purpose is very simple, I wanna use dismax query to search title and
content text fields while I still wanna boost it with another field value
which is the original intetion why the bq params is designed, right?
Does anyone face the same problem?

Hi, Chris, thanks for suggestions.
q=ipod&bq={!dismax qf=userId^0.5 v=$qq}&qq=12345&qt=dismax
I've tried your suggested query above, unfortunately, it does not work out.
I glanced a bit on the error message, the "Infinite Recursion" error seems
that dismax query parser are adding bq multiple times.
