Hi all,
would there be a way to filter matches to a query in such a way that only matches are accepted where (at least) the rarest term in the result occurs in the query.
worded differently: there cannot be any unmatched terms in the result that are rarer than the matching terms.
By rare I mean terms contained in the least amount of documents.
example:
index containing
- foo corp
- bar corp
if I query
spam corp
I want 0 matched: both foo corp and bar corp share the word corp with the query, but they both contain a term that is rarer than corp, so they should be filtered out.
if I query
bar inc
I want bar corp as a match, because bar is the rarest term in the result, and it is matched to the query.
I basically want results that match on their most "unique" part.
I don't immediately see a way to achieve this with scripts.
Kind regards
