By the resulted query toString(), boolean query would not work correctly: qtxt: a foo [1] Multi Field Query (OR) : (title:a body:a) (title:foo body:foo) [2] Multi Field Query (AND): +(title:a body:a) +(title:foo body:foo) [3] Boolean Query : (title:a title:foo) (body:a body:foo) --> By a chance, all are equivalent, returning doc1.
qtxt: a -foo [1] Multi Field Query (OR) : (title:a body:a) -(title:foo body:foo) [2] Multi Field Query (AND): +(title:a body:a) -(title:foo body:foo) [3] Boolean Query : (title:a -title:foo) (body:a -body:foo) --> Here [1,2] "correctly" return no docs, but [3] returns doc1. qtxt: +a +foo [1] Multi Field Query (OR) : +(title:a body:a) +(title:foo body:foo) [2] Multi Field Query (AND): +(title:a body:a) +(title:foo body:foo) [3] Boolean Query : (+title:a +title:foo) (+body:a +body:foo) --> Now [1,2] "correctly" return doc1, but [3] returns no docs. qtxt: a +foo [1] Multi Field Query (OR) : (title:a body:a) +(title:foo body:foo) [2] Multi Field Query (AND): +(title:a body:a) +(title:foo body:foo) [3] Boolean Query : (title:a +title:foo) (body:a +body:foo) --> All "correctly" return doc1. - Doron Daniel Noll <[EMAIL PROTECTED]> wrote on 25/07/2006 23:11:15: > Marvin Humphrey wrote: > > I believe that this will cause difficulties with prohibited terms.
