Difference between q and fq in Solr
solr
Solution
Standard solr queries use the "q" parameter in a request. Filter queries use the "fq" parameter.
The primary difference is that filtered queries do not affect relevance scores; the query functions purely as a filter (docset intersection, essentially).
Problem
Someone please give me a decent explanation of the difference between q and fq in Solr query, covering some points such as - - Do they have the same syntax? - Do they return same results? - When to use which one and why? - Any other differences
