Boosting results on value of field different from query
Hi all
I am using Solr 4.6. I want to query a field for a value but boost the
results based on a different value of another field.
Example search for car rental in products category field but boost results
for car types field with value compact by factor of 10 and sedan by factor
of 5.
I am using the Lucene Standard parser. I added {!edismax bq=type:compact^5
OR type:sedan^10} but that doesn't work.
Regards
Puneet

Hi, Puneet
I think you can try of provided advice from there : http://wiki.apache.org/solr/SolrRelevancyFAQ
Like this one : http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_increase_the_score_for_specific_documents : set index time boos "per document", so set big boos for documents with type:compact and type:sedan
Or this one http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_change_the_score_of_a_document_based_on_the_.2Avalue.2A_of_a_field_.28say.2C_.22popularity.22.29 and http://wiki.apache.org/solr/ExtendedDisMax#bf_.28Boost_Function.2C_additive.29 : use query time function for boosting, you can implement your own function query, called for example "typeBoosting", which will convert "type" value per document from string into boost number and use it like "typeBoosting(type)".

Hi Puneet,
http://localhost:8983/solr/my/select?q=type:sedan^100 type:compact^10
(:*)^1&wt=json&indent=true&fl=,score&debug=results&bf=recip(rord(publish_date),1,2,3)^1.5&sort=score
> desc
Not really. The query I mentioned it does not restrict the other types,
instead it would push other types to bottom of the list as they have lower
score. The query I mentioned, Cars with type sedan listed first, compact
secondly and rest are the bottom of the list.
You would have to control the logic at the application level, which type you
want to be on the top.
In the above query, we are boosting type sedan to be on top, compact below
the sedan types and rest are at the bottom.
Change the those boosting values to get the different results.

Hi Manju
Would this query not be searching for and thus restricting results to type
sedan and compact?
I would like the results to include other types but only show up lower down
the list.

Hi Puneet,
if you type field is pre-determined text field ex type [compact, sedan,
hatchback], I think you have to boost with query type field (q) to
get more accurate boosting.
Ex: http://localhost:8983/solr/my/select?q=type:sedan^100 type:compact^10
(:*)^1&wt=json&indent=true&fl=,score&debug=results&bf=recip(rord(publish_date),1,2,3)^1.5&sort=score
desc
For publish_date, replace with the date you use for getting latest resultes.
In the above query, things to note is that
- fl=,score -> The result set would display score value for each document
- sort by score as first sort field that will give you the documents with
the highest boost value (score) on top
Play around with the boosting values ^100 ^10 (perhaps 5,10,20 ) and
observe how the score value will change the documents.
I'm not really sure how solr calculation works, however the above query
must give you the accurate boosted documents.
