| Called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.
|
|
virtual void | extractTerms (SetTerm terms) |
| Adds all terms occurring in this query to the terms set. Only works if this query is in its rewritten form.
|
|
virtual LuceneObjectPtr | clone (const LuceneObjectPtr &other=LuceneObjectPtr()) |
| Returns a clone of this query.

|
virtual String | toString (const String &field) |

|
virtual int32_t | hashCode () |
| Return hash code for this object.
|
|
virtual double | customScore (int32_t doc, double subQueryScore, Collection< double > valSrcScores) |
| Compute a custom score by the subQuery score and a number of ValueSourceQuery scores.
|
|
virtual double | customScore (int32_t doc, double subQueryScore, double valSrcScore) |
| Compute a custom score by the subQuery score and the ValueSourceQuery score.
|
|
virtual ExplanationPtr | customExplain (int32_t doc, const ExplanationPtr &subQueryExpl, Collection< ExplanationPtr > valSrcExpls) |
| Explain the custom score.
|
|
virtual ExplanationPtr | customExplain (int32_t doc, const ExplanationPtr &subQueryExpl, const ExplanationPtr &valSrcExpl) |
| Explain the custom score.
|
|
virtual WeightPtr | createWeight (const SearcherPtr &searcher) |
| Constructs an appropriate Weight implementation for this query. Only implemented by primitive queries, which re-write to themselves.
|
|
virtual bool | isStrict () |
| Checks if this is strict custom scoring. In strict custom scoring, the ValueSource part does not participate in weight normalization. This may be useful when one wants full control over how scores are modified, and does not care about normalizing by the ValueSource part. One particular case where this is useful if for testing this query.
|
|
virtual void | setStrict (bool strict) |
| Set the strict mode of this query.
|
|
virtual String | name () |
| A short name of this query, used in toString(String) .
|
|
virtual String | toString (const String &field) |
| Prints a query to a string, with field assumed to be the default field and omitted.
|
|
virtual String | toString () |
| Prints a query to a string.
|
|
| Query () |
|
virtual | ~Query () |
|
boost::shared_ptr< Query > | shared_from_this () |
|
virtual void | setBoost (double b) |
| 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.
|
|
virtual double | 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.
|
|
virtual WeightPtr | weight (const SearcherPtr &searcher) |
| Constructs and initializes a Weight for a top-level query.
|
|
virtual QueryPtr | combine (Collection< QueryPtr > queries) |
| Called when re-writing queries under MultiSearcher.
|
|
virtual SimilarityPtr | getSimilarity (const SearcherPtr &searcher) |
| 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.
|
|
String | boostString () |
| Return given boost value as a string.
|
|
virtual | ~LuceneObject () |
|
virtual void | initialize () |
| Called directly after instantiation to create objects that depend on this object being fully constructed.
|
|
virtual int32_t | compareTo (const LuceneObjectPtr &other) |
| Compare two objects.
|
|
virtual | ~LuceneSync () |
|
virtual SynchronizePtr | getSync () |
| Return this object synchronize lock.
|
|
virtual LuceneSignalPtr | getSignal () |
| Return this object signal.
|
|
virtual void | lock (int32_t timeout=0) |
| Lock this object using an optional timeout.
|
|
virtual void | unlock () |
| Unlock this object.
|
|
virtual bool | holdsLock () |
| Returns true if this object is currently locked by current thread.
|
|
virtual void | wait (int32_t timeout=0) |
| Wait for signal using an optional timeout.
|
|
virtual void | notifyAll () |
| Notify all threads waiting for signal.
|
|
Query that sets document score as a programmatic function of several (sub) scores:
-
the score of its subQuery (any query)
-
(optional) the score of its ValueSourceQuery (or queries). For most simple/convenient use cases this query is likely to be a
FieldScoreQuery
Subclasses can modify the computation by overriding getCustomScoreProvider
.
virtual String Lucene::Query::toString |
( |
const String & |
field | ) |
|
|
virtual |
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:
If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
Some of the more complicated queries (eg. span queries) don't have a representation that can be parsed by QueryParser.
Reimplemented from Lucene::Query.
