Public Member Functions | |
ConstantScoreQuery (Filter filter) | |
override Query | Rewrite (IndexReader reader) |
Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys. | |
override void | ExtractTerms (System.Collections.Generic.ISet< Term > terms) |
Expert: adds all terms occuring in this query to the terms set. Only works if this query is in its rewritten form. | |
override Weight | CreateWeight (Searcher searcher) |
Expert: Constructs an appropriate Weight implementation for this query. | |
override System.String | ToString (string field) |
Prints a user-readable version of this query. | |
override bool | Equals (System.Object o) |
Returns true if o is equal to this. | |
override int | GetHashCode () |
Returns a hash code value for this object. | |
override System.Object | Clone () |
Returns a clone of this query. | |
Public Member Functions inherited from Lucene.Net.Search.Query | |
abstract System.String | ToString (System.String field) |
Prints a query to a string, with field assumed to be the default field and omitted. The representation used is one that is supposed to be readable by QueryParser. However, there are the following limitations:
| |
override System.String | ToString () |
Prints a query to a string. | |
virtual Weight | Weight (Searcher searcher) |
Expert: Constructs and initializes a Weight for a top-level query. | |
virtual Query | Combine (Query[] queries) |
Expert: called when re-writing queries under MultiSearcher. | |
virtual Similarity | GetSimilarity (Searcher searcher) |
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. | |
override int | GetHashCode () |
override bool | Equals (System.Object obj) |
Properties | |
virtual Filter | Filter [get] |
Returns the encapsulated filter | |
Properties inherited from Lucene.Net.Search.Query | |
virtual float | Boost [get, set] |
Gets or 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 . The boost is 1.0 by default. | |
Additional Inherited Members | |
Static Public Member Functions inherited from Lucene.Net.Search.Query | |
static Query | MergeBooleanQueries (params BooleanQuery[] queries) |
Expert: merges the clauses of a set of BooleanQuery's into a single BooleanQuery. | |
