Remarks

If a user wishes to turn on rewriting for wildcard queries and doesn't care about performance implications and to automatically just ignore these exceptions and use the default rewriter (non scoring), this syntax can be used:

var criteria = searcher.CreateSearchCriteria(); var luceneCriteria = (LuceneSearchCriteria)criteria; luceneCriteria.QueryParser.SetMultiTermRewriteMethod(BaseLuceneSearcher.ErrorCheckingScoringBooleanQueryRewriteInstance); //Continue using the 'criteria' object to build up the query

Methods

Rewrite(IndexReader, MultiTermQuery)

public override Query Rewrite(IndexReader reader, MultiTermQuery query)

Parameters

reader IndexReader
query MultiTermQuery
