Namespace Lucene.Net.Analysis.Reverse

Filter to reverse token text.

Classes

ReverseStringFilter

Reverse token string, for example "country" => "yrtnuoc".

If Lucene.Net.Analysis.Reverse.ReverseStringFilter.marker is supplied, then tokens will be also prepended by that character. For example, with a marker of \u0001, "country" => "\u0001yrtnuoc". This is useful when implementing efficient leading wildcards search.

You must specify the required Lucene.Net.Util.LuceneVersion compatibility when creating ReverseStringFilter, or when using any of its static methods:

• As of 3.1, supplementary characters are handled correctly
