Re: Boost Query effect with Standard Request Handler
So the bq parameter works with the standard request handler (I don't have to
specify defType=dismax)??
I've been running a few tests and it doesn't seem to be picking up the bq.
I've boosted one of the values very high (like 1000) compared to the other
fields and it doesn't seem to be affecting anything.
We're using Solr 1.3. Is there something else I may be missing (some sort
of config)?

You can boost terms using field:term^2.0 syntax
See http://wiki.apache.org/solr/SolrQuerySyntax and down into http://lucene.apache.org/java/2_4_0/queryparsersyntax.html
for more details.

Hi Hossman,
We are also facing similar issue:
is there any way to boost fields in standard query parser itself?

no ... i'm just a foolish foolish man who says things with a lot of
authority even though i clearly don't know what i'm talking about.
bq isn't supported directly by SearchHandler, and i need to learn to
double check the code before i answer questions about changes i wasn't
intimately involved with :) ... sorry about that.

Ahh shoot!
Ok, I copied the original thread at the bottom for context.
Basically what I need is the bq functionality with the
StandardRequestHandler. I can't use dismax because that requires using qf
and doesn't offer as much flexibility as we need. I have used Erik's
technique of appending an additional clause to the end of all of my queries,
but this doesn't work when a document is missing the field that I'm boosting
on. This is also an AND query, not OR:
name:something AND (searchTier:1^100 OR searchTier:2^50 ...OR
searchTier:0^1)
In the above example, I'd like to be able to leave the searchTier:0 off and
not have to index any documents that have no searchTier with value=0. The
bq does this correctly, putting any documents that match the criteria but
without a searchTier at the bottom.
The reason I brought the question back up is that hossman said:
"as of SOlr 1.3 -- the "SearchHandler" (which superclasses and replaces the
old StandardRequestHandler and the DisMaxRequestHandler) supports the "bq"
param direclty ... so you can just add a bq param to your request and it
will do what you want."
I tried it and it didn't work, so I was curious if I was still doing
something wrong.

bq only works with dismax (&defType=dismax). To get the same effect
with the lucene/solr query parser, append a clause to the original
query (OR'ing it in).

Hi,
It's hard to tell what you are replying to since you removed the original email (sounds like somebody suggested using bq).
I think it might help if you send the actual URL you are using.
