The PrefixQuery type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | PrefixQuery | Constructs a query for terms starting with  CopyC#prefix |
Methods
| Name | Description | |
|---|---|---|
| ClearTotalNumberOfTerms | Expert: Resets the counting of unique terms.
Do this before executing the query/filter.
(Inherited from MultiTermQuery.) |
| Clone | Returns a clone of this query. (Inherited from 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()).
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.
(Inherited from Query.) |
| CreateWeight | Expert: Constructs an appropriate Weight implementation for this query.
Only implemented by primitive queries, which re-write to themselves.
(Inherited from Query.) |
| Equals | (Overrides MultiTermQuery..::..Equals(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.
(Inherited from Query.) |
 | Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetBoost | Gets the boost for this clause. Documents matching
this clause will (in addition to the normal weightings) have their score
multiplied by (Inherited from Query.)CopyC#b |
| GetEnum | (Overrides MultiTermQuery..::..GetEnum(IndexReader).) |
| GetHashCode | (Overrides MultiTermQuery..::..GetHashCode()()()().) |
| GetPrefix | Returns the prefix of this query. |
| GetRewriteMethod | (Inherited from MultiTermQuery.) |
| 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.
(Inherited from Query.) |
| GetTerm | Obsolete. Returns the pattern term. (Inherited from MultiTermQuery.) |
| GetTotalNumberOfTerms | 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.
(Inherited from MultiTermQuery.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IncTotalNumberOfTerms | (Inherited from MultiTermQuery.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Rewrite | (Inherited from MultiTermQuery.) |
| SetBoost | Sets the boost for this query clause to (Inherited from Query.)CopyC#b CopyC#b |
| SetRewriteMethod | 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}.
(Inherited from MultiTermQuery.) |
| ToString()()()() | Prints a query to a string. (Inherited from Query.) |
| ToString(String) | Prints a user-readable version of this query. (Overrides MultiTermQuery..::..ToString(String).) |
| Weight | Expert: Constructs and initializes a Weight for a top-level query. (Inherited from Query.) |
Fields
| Name | Description | |

 | rewriteMethod | (Inherited from MultiTermQuery.) |
