How to boost score of particular field in a copy field?

[bbarani <bb...@gmail.com>]

Hi,

I have 10 fields copied in to a single copy field for default search. I am
trying to boost one particular field in that copy field, but I am not sure
how boosting in copy field work. Can someone let me know how boosting works
in copy field?

Thanks,
BB

Have you tried simply searching across all 30
fields using (e)dismax? You can set this up in
a request handler in solrconfig.xml and forget
about it.

You could also de-boost the copied-to field
by using a boost < 1 (but > 0, e.g. 0.5).

Thanks a lot for your reply!!

This is the problem I face now when using dismax.

I have almost 30 fields (Some are dynamic fields from database) copied in to
copy field that is being used for default search. Now when I search using
dismax I need to include the boost for all the fields in the search query
else it returns only the result corresponding to the field in qf.

http://localhost:8983/solr/db/select?q=Stanley,%20robert&defType=dismax&qf=name

I get just one result for above query

http://localhost:8983/solr/db/select?q=Stanley,%20robert&defType=dismax&qf=name
lastupdatedBy

Now the search happens across 2 fields.

I want to boost a particular field but at the same time I want the results
that matches keyword from other fileds too.

Thanks,
BB

What you should consider is to use the edismax (or dismax) query parser and 
then you can boost the individual fields. That's a major part of its reason 
for existence - to overcome the limitation of copyField that you mention.
