Dynamically boost search scores

[Brian Lamb <br...@journalexperts.com>]

Hi all,

I have a field in my schema called boost_score. I would like to set it up so
that if I pass in a certain flag, each document score is boosted by the
number in boost_score.

For example if I use:

http://localhost/solr/search/?q=dog

I would get search results like normal. But if I use:

http://localhost/solr/search?q=dog&boost=true

The score of each document would be boosted by the number in the field
boost_score.

Unfortunately, I have no idea how to implement this actually but I'm hoping
that's where you all can come in.

Thanks,

Brian Lamb

bf belongs to DisMaxParams. 

Instead try this  q={!boost b=boost_score}dog

You can use any valid FuctionQuery as a b paramter.

http://lucene.apache.org/solr/api/org/apache/solr/search/BoostQParserPlugin.html

You may want to use parameter referencing also. Where q is harcoded in solrconfig.xml, something like:

q={!boost b=$bb v=$qq}&qq=dog&bb=%22ord%28sum%28boost_score,1%29%29

Thank you for the advice. I looked at the page you recommended and came up
with:

http://localhost:8983/solr/search/?q=dog&fl=boost_score,genus,species,score&rows=15&bf=%22ord%28sum%28boost_score,1%29%29
^10%22

But appeared to have no effect. The results were in the same order as they
were when I left off the bf parameter. So what am I doing incorrectly?

Thanks,

See boosting documents by function query. This way you can use document's 
boost_score field to affect the final score.
