Re: **SPAM** Re: boosting injection
Hi Ken,
thanks for your response...unfortunately it doesn't solve my problem.
I cannot chnage the client behaviour so the query must be a query and not only the query terms.
In this scenario, It would be great, for example, if I could declare the boost in the schema field definition....but I think it's not possible isn't it?
Regards
Andrea

Andrea,
Using the SOLR dismax query handler, you could set up queries like this to
boost on fields of your choice. Basically, the q parameter would be the
query terms (without the field definitions, and a qf (Query Fields)
parameter that you use to define your boost(s):
http://wiki.apache.org/solr/DisMaxQParserPlugin. A non-SOLR alternative
would be to parse the query in whatever application is sending the queries
to the SOLR instance to make the necessary transformations.

Ken

Hi Ken,
yes I'm a java developer so I think I should be able to do that but I
was wondering if there's a way to solve my issue without coding.
Problem is that I need to adjust this query in a short time and in
addition I cannot justify (at this stage of the project) additional
software artifacts.
Anyway thanks for your support
Best Regards,
Andrea

Andrea,
Another approach, aside of Markus' suggestion, would be to create your own
handler that could intercept the query and perform whatever necessary
transformations that you need at query time. However, that would require
having Java knowledge (which I make no assumption).

Ken

Re: boosting injection

The main disadvantage of index-time boosting is that you must reindex your
corpus entirely if you want to alter the boost factors. And there's no very
good
way to anticipate what boost factors will give you the results you want....
I wonder if you could cheat and do some basic string processing on the
query and add your boosts? That's be tricky unless you have very predictable
strings....

Y-E-A-H! I think it's so!
Markus, what are disadvantages of this boosting strategy?
Thanks a lot

Index-time boosting maybe?
