BooleanQuery.SetMinimumNumberShouldMatch Method 

Specifies a minimum number of the optional BooleanClauses which must be satisfied.

By default no optional clauses are necessary for a match (unless there are no required clauses). If this method is used, then the specified number of clauses is required.

Use of this method is totally independent of specifying that any specific clauses are required (or prohibited). This number will only be compared against the number of matching optional clauses.

EXPERT NOTE: Using this method may force collecting docs in order, regardless of whether setAllowDocsOutOfOrder(true) has been called.
