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).

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
