QueryNodeProcessor |
QueryParserHelper.getQueryNodeProcessor()
Returns the processor object used to process the query node tree, it
returns
null if no processor is used. |

void |
QueryParserHelper.setQueryNodeProcessor(QueryNodeProcessor processor)
Sets the processor that will be used to process the query node tree.
|
Constructor and Description |
---|
QueryParserHelper(QueryConfigHandler queryConfigHandler,
SyntaxParser syntaxParser,
QueryNodeProcessor processor,
QueryBuilder builder)
Creates a query parser helper object using the specified configuration,
text parser, processor and builder.
|
Modifier and Type | Class and Description |
---|---|
class |
NoChildOptimizationQueryNodeProcessor
A
NoChildOptimizationQueryNodeProcessor removes every
BooleanQueryNode, BoostQueryNode, TokenizedPhraseQueryNode or
ModifierQueryNode that do not have a valid children. |
class |
QueryNodeProcessorImpl
This is a default implementation for the
QueryNodeProcessor
interface, it's an abstract class, so it should be extended by classes that
want to process a QueryNode tree. |
class |
QueryNodeProcessorPipeline
A
QueryNodeProcessorPipeline class should be used to build a query
node processor pipeline. |
class |
RemoveDeletedQueryNodesProcessor
A
QueryNodeProcessorPipeline class removes every instance of
DeletedQueryNode from a query node tree. |
Modifier and Type | Method and Description |
---|---|
QueryNodeProcessor |
QueryNodeProcessorPipeline.get(int index) |
QueryNodeProcessor |
QueryNodeProcessorPipeline.remove(int index) |
QueryNodeProcessor |
QueryNodeProcessorPipeline.set(int index,
QueryNodeProcessor processor) |
Modifier and Type | Method and Description |
---|---|
Iterator<QueryNodeProcessor> |
QueryNodeProcessorPipeline.iterator() |
ListIterator<QueryNodeProcessor> |
QueryNodeProcessorPipeline.listIterator() |
ListIterator<QueryNodeProcessor> |
QueryNodeProcessorPipeline.listIterator(int index) |
List<QueryNodeProcessor> |
QueryNodeProcessorPipeline.subList(int fromIndex,
int toIndex) |
Modifier and Type | Method and Description |
---|---|
void |
QueryNodeProcessorPipeline.add(int index,
QueryNodeProcessor processor) |
boolean |
QueryNodeProcessorPipeline.add(QueryNodeProcessor processor) |
QueryNodeProcessor |
QueryNodeProcessorPipeline.set(int index,
QueryNodeProcessor processor) |
Modifier and Type | Method and Description |

QueryNodeProcessorPipeline.addAll(Collection<? extends QueryNodeProcessor> c) |
boolean |
QueryNodeProcessorPipeline.addAll(int index,
Collection<? extends QueryNodeProcessor> c) |
Modifier and Type | Class and Description |
---|---|
class |
BooleanModifiersQueryNodeProcessor
This processor is used to apply the correct
ModifierQueryNode to BooleanQueryNode s children. |
class |
PrecedenceQueryNodeProcessorPipeline
This processor pipeline extends
StandardQueryNodeProcessorPipeline and enables
boolean precedence on it. |
Modifier and Type | Class and Description |
---|---|
class |
AllowLeadingWildcardProcessor
This processor verifies if
StandardQueryConfigHandler.ConfigurationKeys.ALLOW_LEADING_WILDCARD is defined in the
QueryConfigHandler . |
class |
AnalyzerQueryNodeProcessor
This processor verifies if
StandardQueryConfigHandler.ConfigurationKeys.ANALYZER
is defined in the QueryConfigHandler . |
class |
BooleanQuery2ModifierNodeProcessor
This processor is used to apply the correct
ModifierQueryNode to
BooleanQueryNode s children. |
class |
BooleanSingleChildOptimizationQueryNodeProcessor
This processor removes every
BooleanQueryNode that contains only one
child and returns this child. |
class |
BoostQueryNodeProcessor
This processor iterates the query node tree looking for every
FieldableNode that has StandardQueryConfigHandler.ConfigurationKeys.BOOST in its
config. |
class |
DefaultPhraseSlopQueryNodeProcessor
This processor verifies if
StandardQueryConfigHandler.ConfigurationKeys.PHRASE_SLOP
is defined in the QueryConfigHandler . |
class |
FuzzyQueryNodeProcessor
This processor iterates the query node tree looking for every
FuzzyQueryNode , when this kind of node is found, it checks on the
query configuration for
StandardQueryConfigHandler.ConfigurationKeys.FUZZY_CONFIG , gets the
fuzzy prefix length and default similarity from it and set to the fuzzy node. |
class |
MatchAllDocsQueryNodeProcessor
This processor converts every
WildcardQueryNode that is "*:*" to
MatchAllDocsQueryNode . |
class |
MultiFieldQueryNodeProcessor
This processor is used to expand terms so the query looks for the same term
in different fields.
|
class |
MultiTermRewriteMethodProcessor
This processor instates the default
MultiTermQuery.RewriteMethod ,
MultiTermQuery.CONSTANT_SCORE_REWRITE , for multi-term
query nodes. |
class |
OpenRangeQueryNodeProcessor
Processes
TermRangeQuery s with open ranges. |
class |
PhraseSlopQueryNodeProcessor
This processor removes invalid
SlopQueryNode objects in the query
node tree. |
class |
PointQueryNodeProcessor
This processor is used to convert
FieldQueryNode s to
PointRangeQueryNode s. |
class |
PointRangeQueryNodeProcessor
This processor is used to convert
TermRangeQueryNode s to
PointRangeQueryNode s. |
class |
RegexpQueryNodeProcessor
Processor for Regexp queries.
|
class |
RemoveEmptyNonLeafQueryNodeProcessor
This processor removes every
QueryNode that is not a leaf and has not
children. |
class |
StandardQueryNodeProcessorPipeline
This pipeline has all the processors needed to process a query node tree,
generated by
StandardSyntaxParser , already assembled. |
class |
TermRangeQueryNodeProcessor
This processors process
TermRangeQueryNode s. |
class |
WildcardQueryNodeProcessor
The
StandardSyntaxParser creates PrefixWildcardQueryNode nodes which
have values containing the prefixed wildcard. |
