Constructor Details

LuceneQueryParser

public LuceneQueryParser(String f,
 org.apache.lucene.analysis.Analyzer a)

Creates a new ExtendableQueryParser instance

Parameters:

f - the default query field

a - the analyzer used to find terms in a query string

Method Details

getFieldQuery

protected org.apache.lucene.search.Query getFieldQuery(String field,
 String queryText,
 boolean quoted)
                                                throws org.apache.lucene.queryparser.classic.ParseException

Overrides the field query creation to handle quoted queries specially. For quoted queries on the default field, creates a phrase query instead of a term query.

Overrides:

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

Parameters:

field - the field to query

queryText - the query text

quoted - whether the query is quoted

Returns:

the created Query object

Throws:

org.apache.lucene.queryparser.classic.ParseException - if the query cannot be parsed

splitField

protected org.apache.lucene.queryparser.ext.Extensions.Pair<String,String> splitField(String defaultField,
 String field)

Splits a field name into its components.

Parameters:

defaultField - the default field name

field - the field name to split

Returns:

a Pair containing the field name and extension key
