Solr Boost returns unexpected results
-------------------------------------
Key: SOLR-2131
URL: https://issues.apache.org/jira/browse/SOLR-2131
Project: Solr
Issue Type: Wish
Reporter: Jayant Patil
Hi,
We are using Solr for our searches. We are facing issues while applying boost
on particular fields.
E.g.
We have a field Category, which contains values like Electronics, Computers,
Home Appliances, Mobile Phones etc.
We want to boost the category Electronics and Mobile Phones, we are using the
following query
(category:Electronics^2 OR category:Mobile Phones^1 OR category:[* TO *]^0)
The results are unexpected as Category Mobile Phones gets more boost than
Electronics even if we are specifying the boost factor 2 for electronics and 1
for mobile phones respectively.
On debugging we found that DocFreq is manipulating the scores and hence
affecting the overall boost. The no. of docs for mobile phones is much lower
than that for electronics and solr is giving higher score to mobile phones for
this reason.
Please suggest a solution.
