The methods of the Query class are listed below. For a complete list of Query class members, see the Query Members topic.
Public Static Methods
Public Instance Methods
 Clone | Returns a clone of this query. |
| Combine | 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() and RangeQuery.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. |
| Equals (inherited from Object) | Determines whether the specified Object is equal to the current Object. |
| ExtractTerms | Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its {@link #rewrite rewritten} form. |
| GetBoost | Gets the boost for this clause. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by b. The boost is 1.0 by default. |
| GetHashCode (inherited from Object) | Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. |
| GetSimilarity | 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. |
| GetType (inherited from Object) | Gets the Type of the current instance. |
| Rewrite | Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys. |
| SetBoost | Sets the boost for this query clause to b. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by b. |
| ToString | Overloaded. |
| Weight | Expert: Constructs and initializes a Weight for a top-level query. |
Protected Instance Methods
 Finalize (inherited from Object) | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. |
| MemberwiseClone (inherited from Object) | Creates a shallow copy of the current Object. |
