In other words, all the query's terms must appear, but it doesn't matter in what fields they appear.

If x fields are specified, this effectively constructs:

            <code>
            (field1:query1) (field2:query2) (field3:query3)...(fieldx:queryx)
            </code>
            

            Usage:
            
CopyC#
String[] fields = {"filename", "contents", "description"};
BooleanClause.Occur[] flags = {BooleanClause.Occur.SHOULD,
BooleanClause.Occur.MUST,
BooleanClause.Occur.MUST_NOT};
MultiFieldQueryParser.parse("query", fields, flags, analyzer);

The code above would construct a query:

CopyC#
(filename:query) +(contents:query) -(description:query)

            Usage:
            
CopyC#
String[] query = {"query1", "query2", "query3"};
String[] fields = {"filename", "contents", "description"};
BooleanClause.Occur[] flags = {BooleanClause.Occur.SHOULD,
BooleanClause.Occur.MUST,
BooleanClause.Occur.MUST_NOT};

When set, result phrase and multi-phrase queries will be aware of position increments. Useful when e.g. a StopFilter increases the position increment of the token that follows an omitted token.

Default: false.

WARNING: Setting the rangeCollator to a non-null collator using this method will cause every single index Term in the Field referenced by lowerTerm and/or upperTerm to be examined. Depending on the number of index Terms in this Field, the operation could be very slow.
