Hi all,
I'm trying to achieve the following, and wondered if I could get
feedback on how best to achieve it.
Given an example phrase P - "Squeamish Ossifrage Monster", I'd like to
search a corpus such that in a list of results,
- Docs with all 3 words in the phrase are ranked at the top
- Docs with atleast 2 of the words in that order are ranked next
-- (Say, "Ossifrage Monster" and "Squeamish Ossifrage" but not
"Squeamish Monster")
- Docs with only one of the words come next
-- Is there a way to put these into one result set, and the first 2
kinds in another?
The naive solution of course would be to take a phrase P, and then
separate out all its terms (Pt_1, Pt_2, Pt_3) and then do those 3
searches manually - seems like a colossal waste.
Is this possible with SpanQuery in some way? I also came across an
article somewhere which said that QueryParser doesn't support SpanQuery
- in which case, what would be the best way to actually implement this?
Cheers
Viksit
