Re: query bag of word with negation
Queries of the form *some* can be _quite_ expensive, make sure you
test on a realistic corpus.
ngrams are often used to solve that problem.
If you mean *some then you may want to include ReverseWildcardFilterFactory

Re: query bag of word with negation
Hello Markus
Thanks !
The ComplexPhraseQueryParser syntax:
q={!complexphrase inOrder=false}collector:"wonderful pizza -peperoni"~5
answers my needs.
BTW,
Apparently it accepts both leading/ending wildcards, that's look powerful
feature.
Any chance it would support the "sow=false" in order to combine with
multi-word synonyms ?
