Andrzej Bialecki commented on LUCENE-1813:
-------------------------------------------
+1. One comment, perhaps stating the obvious .. I picked char 0001 for two
reasons - it's not likely to be used in regular text, and its UTF-8 encoding
uses one byte. The use case for this filter means that it will create more or
less as many tokens as there were in the original token stream, thus doubling
the size of term dictionary. One byte here, one byte there, and suddenly it
matters whether we use 0001 or FFFF ...
> Add option to ReverseStringFilter to mark reversed tokens

> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/analyzers
> Affects Versions: 2.9
> Reporter: Andrzej Bialecki
> Assignee: Robert Muir
> Fix For: 2.9

> Attachments: LUCENE-1813.patch, reverseMark-2.patch, reverseMark.patch

> This patch implements additional functionality in the filter to "mark"
> reversed tokens with a special marker character (Unicode 0001). This is
> useful when indexing both straight and reversed tokens (e.g. to implement
> efficient leading wildcards search).
