public class LuxQueryParser
extends org.apache.lucene.queryparser.ext.ExtendableQueryParser

A Lucene query parser extension that supports query terms of the form:

[node]<[nodeName]:[term]

In which nodeName is either empty, an unqualified element name, a prefixed element name (ie a QName), or a QName prefixed with "@", indicating an attribute. nodeName is optional: if it is not present, a full text query of the entire document is indicated. The "node" prefix is also optional. Concrete examples:

  node<:"Alas, poor Yorick"
  node
 
 AND
 
 Boolean queries containing a marker term: lux_within:{slop} or lux_near:{slop} will be
 replaced by a SpanNearQuery, if the term is required, or a SpanOrQuery, otherwise.  Note
 that all BooleanQueries nested inside a marked query must also themselves be marked (as a Span).

Constructor Detail

LuxQueryParser

public LuxQueryParser(org.apache.lucene.util.Version matchVersion,
              String f,
              org.apache.lucene.analysis.Analyzer a,
              org.apache.lucene.queryparser.ext.Extensions ext,
              NodeQueryBuilder queryBuilder)

Method Detail

makeLuxQueryParser

public static LuxQueryParser makeLuxQueryParser(IndexConfiguration config)

bindNamespacePrefix

public void bindNamespacePrefix(String prefix,
                       String namespaceURI)

declares a namespace binding.

Parameters:

prefix - The namespace prefix to bind. No attempt is made to ensure that the prefix is syntactically valid. It is not possible to declare a default namespace using this API: the default namespace is always no namespace in this query syntax. If this method is called with a null or empty prefix, the effect is undefined.

namespaceURI - The namespace "URI" to bind. If empty or null, any existing binding for the prefix is removed.

clearNamespaces

public void clearNamespaces()

parse

public org.apache.lucene.search.Query parse(String queryString)
                                     throws org.apache.lucene.queryparser.classic.ParseException

Overrides:

parse in class org.apache.lucene.queryparser.classic.QueryParserBase

Throws:

org.apache.lucene.queryparser.classic.ParseException

escapeQParser

public static final String escapeQParser(String s)
