I've created an Analyzer that performs a few filtering tasks, including
creating Shingles and term Replacements among other things.
I use that Analyzer with IndexWriter and it works as expected. but when

say you index information about a book with the title: "Lucene in
Action" with an ID and other information.
searching for "Lucene" will find the book and will give you the book's
ID. now if you used Store.YES -- then Lucene can also give you the full
title, i.e. "Lucene in Action", but if you

ShingleFilter with position increment > 1 and then filtering tokens containing
"_" (underscore). This will be easier, I guess.

I'm no expert but my understanding is that it is Searchable, but you can
Not retrieve the information, if for example you want to show excerpts

In the code you will see a switch for the characters.
