Method Detail

createNumericRangeQuery

public static org.apache.lucene.search.Query createNumericRangeQuery(String fieldName,
                                                                     Object from,
                                                                     Object to,
                                                                     boolean includeLower,
                                                                     boolean includeUpper)

createExactMatchQuery

public static org.apache.lucene.search.Query createExactMatchQuery(String fieldName,
                                                                   Object value)

Will create a RangeQuery matching exactly the provided value: lower and upper value match, and bounds are included. This should perform as efficiently as a TermQuery.

Parameters:

fieldName -

value -

Returns:

the created Query

setNumericValue

public static void setNumericValue(Object value,
                                   org.apache.lucene.document.NumericField numericField)
