Re: Boosting specific field value
Actually, I _think_ you need to use a nested query for my idea, you can
just use "LocalParams".
&q={!lucene} your query in lucene syntax
I think that'll work, I think you can use "LocalParams" directly in the
'q', no need for nested query. If it will, it avoids the escaping
nightmares with nested queries.

What gets really confusing there is that the nested query expression needs
to be in quotes -- so if you need quotes within the actual query itself (say
for a phrase), you need to escape them. And the whole thing needs to be
URI-encoded, of course. It does get confusing, but is quite powerful.

Hi Ravi,
with dismax, use the parameter "q.alt" which expects standard lucene
syntax (instead of "q"). If "q.alt" is present in the query, "q" is not
required. Add the parameter "qt=dismax".

Erick,
I afraid you misinterpreted my issueif I query like you
said
i.e q=source(bbc OR "associated press")^10 I will ONLY get documents
with
source BBC or Associated Press...what I am asking is - if my query
query
does not deal with source at all but uses some other field...since the
field
"source" will be in the result , is there a way to still boost such a
document
To re-iterate, If my query is as follows
q=primarysection:(Politics* OR Nation*)&fq=contenttype:("Blog" OR
"Photo
Gallery") pubdatetime:[NOW-3MONTHS TO NOW]
and say the resulting docs have "source" field, is there any way I can
boost
the resulting doc/docs that have either BBC/Associated Press as the
value
in
source field to be on top
Can a filter query (fq) have a boost ? if yes, then probably I could
rewrite
the query as follows in a round about way
q=primarysection:(Politics* OR Nation*)&fq=contenttype:("Blog" OR

Theoretically, I have to write source in the fq 2 times as I need docs
that
have source values too just that they will have a lower boost

RE: Boosting specific field value
Nice, I didn't know about q.alt. Or, alternately, yes, you could use a nested
query, good call. Which, yes, I agree is kind of confusing at first.
&qt=dismax # use dismax for the overall query
&bq=whatever # so we can use bq, since we're using dismax
&q=_query_:"{!lucene} solr-lucene syntax query" # but now make our entire 'q' a

Can a filter query (fq) have a boost ? if yes, then probably I could rewrite

Theoretically, I have to write source in the fq 2 times as I need docs that
