Hello Solr Community!
*Problem*: I wish to know if the result document matched all the terms in
the query. The ranking used in solr works most of the time. For some cases
where one of the term is rare and occurs in couple of fields; such
documents trump a document which matches all the terms. Ideally i wish to
have such a document (that matches all terms) to trump a document that
matches only 9/10 terms but matches one of the rare terms twice.
eg:
*query1*
field1:(a b c d) field2:(a b c d)
Results of the above query looks good.
*query2*
filed1:(a b c 5) field2:(a b c 5)
result:
doc1: {field1: b c 5 field2: b c 5}
....
doc21: {field1: a b c 5 field: null}
Results are almost good except that doc21 is trailing doc1. There are a few
documents similar to doc1 and pushes doc21 to next page (I use default page
size = 10)
I understand that this is how tf-idf works. I tried to boost certain fields
to solve this problem. But that breaks normal cases (query1). So, I set out
to just solve the case where I wish to boost (or) augment a field with that
information (as ratio of matched-terms/total-terms)
*Ask:* Is it possible to get back the terms of the query and the matched
state ?
I tried
- debug=query option (with the default select handler)
- with terms in the debug response I could write a function query to
know its match state
Is this approach safe/performant for production use ? Is there a better
approach to solve this problem ?
