Method Detail

getFuzzyQuery

protected Query getFuzzyQuery(String field,
                              String termStr,
                              float minSimilarity)
                       throws ParseException

Description copied from class: QueryParser

Factory method for generating a query (similar to QueryParser.getWildcardQuery(java.lang.String, java.lang.String)). Called when parser parses an input term token that has the fuzzy suffix (~) appended.

Overrides:

getFuzzyQuery in class QueryParser

Parameters:

field - Name of the field query will use.

termStr - Term token to use for building term for the query

Returns:

Resulting Query built for the term

Throws:

ParseException - throw in overridden method to disallow

getWildcardQuery

protected Query getWildcardQuery(String field,
                                 String termStr)
                          throws ParseException

Description copied from class: QueryParser

Factory method for generating a query. Called when parser parses an input term token that contains one or more wildcard characters (? and *), but is not a prefix term token (one that has just a single * character at the end)

Depending on settings, prefix term may be lower-cased automatically. It will not go through the default Analyzer, however, since normal Analyzers are unlikely to work properly with wildcard templates.

Can be overridden by extending classes, to provide custom handling for wildcard queries, which may be necessary due to missing analyzer calls.

Overrides:

getWildcardQuery in class QueryParser

Parameters:

field - Name of the field query will use.

termStr - Term token that contains one or more wild card characters (? or *), but is not simple prefix term

Returns:

Resulting Query built for the term

Throws:

ParseException - throw in overridden method to disallow
