I see my tables didn't come through so well. Here's (I hope) a plain
text version:
I understand that it would be best to have a UI that mapped lists of
terms to MUST, MUST_NOT and SHOULD, but I'm currently constrained to
using the QueryParser with boolean operators.
Given that, I was thinking that the addition of "*:*" (in 2.1) to
represent MatchAllDocsQuery might help solve:
" NOT Chair " is the problem ... you can't have a negative
clause in isolation by itself -- it doesn't make sense because
there isn't anything positively selecting results for you to then
exclude results from.
by making that: "*:* NOT Chair"
To test, I indexed these documents:
DocID Body Value
----- ----------
0 A B C
1 A B C D
2 A C D
3 B C D
4 C D
5 B
Expected Actual
Query Parsed As Matches Matches
----- --------- -------- -------
NOT B -body:B 2, 4 <none>
*:* NOT B MatchAllDocsQuery -body:B 2, 4 2, 4, 5
*.* AND NOT B +MatchAllDocsQuery -body:B 2, 4 2, 4, 5
Can someone explain why doc 5 is matched for both "*:* NOT B" and
"*.* AND NOT B"?
Are my Expected Matches incorrect?
Thanks, david
