Interface | Description |
---|---|
QueryNodeProcessor |
A
QueryNodeProcessor is an interface for classes that process a
QueryNode tree. |
Class | Description |
---|---|
NoChildOptimizationQueryNodeProcessor |
A
NoChildOptimizationQueryNodeProcessor removes every
BooleanQueryNode, BoostQueryNode, TokenizedPhraseQueryNode or
ModifierQueryNode that do not have a valid children. |
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. |
QueryNodeProcessorPipeline |
A
QueryNodeProcessorPipeline class should be used to build a query
node processor pipeline. |
RemoveDeletedQueryNodesProcessor |
A
QueryNodeProcessorPipeline class removes every instance of
DeletedQueryNode from a query node tree. |
The package org.apache.lucene.queryParser.processors contains interfaces that should be implemented by every query node processor.
The interface that every query node processor should implement is QueryNodeProcessor
.
A query node processor should be used to process a QueryNode
tree.
QueryNode
trees can be programmatically created or generated by a
text parser. See org.apache.lucene.queryparser.flexible.core.parser
for more details about text parsers.

A pipeline of processors can be assembled using QueryNodeProcessorPipeline
.
Implementors may want to extend QueryNodeProcessorImpl
, which simplifies
the implementation, because it walks automatically the QueryNode
. See
QueryNodeProcessorImpl
for more details.
