: What's the difference between the "AND" and the "+" boolean operators. Also : the "NOT" and "-" boolean operators? Are each of these pair of operators : functionally equivalent? : : >From the examples provided in the Query Syntax documentation at: : http://lucene.apache.org/java/docs/queryparsersyntax.html#Boolean%20operators : it looks as if these are the same.
this doc may be of use to you... http://wiki.apache.org/lucene-java/BooleanQuerySyntax In a nut shell: BooleanQuery is not really boolean ... prefix + and - corrispond directly to the MUST and MUST_NOT operators of a BooleanClause ... AND, OR and NOT make best attempts at mapping singular clause rules to boolean operators. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
