Description
test:
[junit] Testsuite: org.apache.lucene.search.TestAornotB
[junit] Tests run: 3, Failures: 1, Errors: 0, Time elapsed: 0.39 sec
[junit] ------------- Standard Output ---------------
[junit] Doc1 = A B C
[junit] Doc2 = A B C D
[junit] Doc3 = A C D
[junit] Doc4 = B C D
[junit] Doc5 = C D
[junit] -------------------------------------------------
[junit] With query "A OR NOT B" we expect to hit
[junit] all documents EXCEPT Doc4, instead we only match on Doc3.
[junit] While LUCENE currently explicitly does not support queries of
[junit] the type "find docs that do not contain TERM" - this explains
[junit] not finding Doc5, but does not justify elimnating Doc1 and Doc2
[junit] -------------------------------------------------
[junit] the fix shoould likely require a modification to QueryParser.jj
[junit] around the method:
[junit] protected void addClause(Vector clauses, int conj, int mods, Query q)
[junit] Query:c:a -c:b hits.length=1
[junit] Query Found:Doc[0]= A C D
[junit] 0.0 = (NON-MATCH) Failure to meet condition(s) of required/prohibited clause(s)

[junit] 1.2231436 = idf(docFreq=3)
[junit] 0.5 = fieldNorm(field=c, doc=1)
[junit] 0.0 = match on prohibited clause (c:b)
