Expert: called when re-writing queries under MultiSearcher. Create a single query suitable for use by all subsearchers (in 1-1 correspondence with queries). This is an optimization of the OR of all queries. We handle the common optimization cases of equal queries and overlapping clauses of boolean OR queries (as generated by MultiTermQuery.rewrite()). Be careful overriding this method as queries[0] determines which method will be called and is not necessarily of the same type as the other queries.

Returns true if

CopyC#

o

is equal to this.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Gets the boost for this clause. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by

CopyC#

b

. The boost is 1.0 by default.

Returns a hash code value for this object.

Expert: Returns the Similarity implementation to be used for this query. Subclasses may override this method to specify their own Similarity implementation, perhaps one that delegates through that of the Searcher. By default the Searcher's Similarity implementation is returned.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Sets the boost for this query clause to

CopyC#

b

. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by

CopyC#

b

.

Prints a query to a string.

Expert: Constructs and initializes a Weight for a top-level query.
