Solr search query for advanced search

Question

I'm using solr 4.2. And I've implemented Advanced search in my application. In this search, one option is there for 'include all these words'. so whenever i put any word or any phrase without stop words, it works fine but with stop words, it returns no result. For example: Query: purchase tune This query works fine but if i put query like:'i would like to purchase tune' then it gives no results. Why is so? And what i need to do? Also for this kind of search I was using 'mm' parameter in solr. But now using 'q.op'.

In solr i'm adding param q.op as following params.add("q.op","AND"); and query as params.add("q",query);

can you show us the query you use and the field definition that you use it on? — Maurizio In denmark
@MaurizioIndenmark: just edited the question and shown how m adding params — Forum User
remeber that an AND is very strict. how is the result you are expecting to get back? — Maurizio In denmark

Do you encounter the problem with the Dismax Handler and the mm parameter?

The DisMax handler has an issue with stopwords: https://issues.apache.org/jira/browse/SOLR-3085

In this ticket you find some workarounds:

Typical solution is to not use stopwords or harmonize stopword lists across all fields in your QF, or relax the MM to a lower percentag. Sometimes these are not acceptable workarounds, and we should find a better solution.

Perhaps "harmonize stopword lists" is a suitable soluation for your problem.
