    • setMinimumNumberShouldMatch

      public BooleanQuery.Builder setMinimumNumberShouldMatch(int min)
      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.

      Parameters:
      min - the number of optional clauses that must match

    • add

      public BooleanQuery.Builder add(BooleanClause clause)
      Add a new clause to this BooleanQuery.Builder. Note that the order in which clauses are added does not have any impact on matching documents or query performance.
      Throws:
      IndexSearcher.TooManyClauses - if the new number of clauses exceeds the maximum clause number

    • add

      public BooleanQuery.Builder add(Query query, BooleanClause.Occur occur)
      Add a new clause to this BooleanQuery.Builder. Note that the order in which clauses are added does not have any impact on matching documents or query performance.
      Throws:
      IndexSearcher.TooManyClauses - if the new number of clauses exceeds the maximum clause number

    • build

      public BooleanQuery build()
      Create a new BooleanQuery based on the parameters that have been set on this builder.
