Initializes a new instance of the RegexQuery class

Expert: Resets the counting of unique terms. Do this before executing the query/filter.

Returns a clone of this query.

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.

Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.

Indicates whether the current object is equal to another object of the same type.

Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its {@link #rewrite rewritten} form.

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.

Construct the enumeration to be used, expanding the pattern term.

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.

Returns the pattern term.

Expert: Return the number of unique terms visited during execution of the query. If there are many of them, you may consider using another query type or optimize your total term count in index.

This method is not thread safe, be sure to only call it when no query is running! If you re-use the same query instance for another search, be sure to first reset the term counter with {@link #clearTotalNumberOfTerms}.

On optimized indexes / no MultiReaders, you get the correct number of unique terms for the whole index. Use this number to compare different queries. For non-optimized indexes this number can also be achived in non-constant-score mode. In constant-score mode you get the total number of terms seeked for all segments / sub-readers.

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

.

Sets the rewrite method to be used when executing the query. You can use one of the four core methods, or implement your own subclass of {@link RewriteMethod}.

Prints a query to a string.

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