Subject Re: Applying Tokenizers and Filters to CopyFields
Date Wed, 25 Mar 2015 21:52:10 GMT
I agree the terminology is possibly a little confusing.

Stored refers to values that are stored verbatim. You can retrieve them
verbatim. Analysis does not affect stored values.
Indexed values are tokenized/transformed and stored inverted. You can't
recover the literal analyzed version (at least, not easily).

If what you really want is to store and retrieve case folded versions of
your data as well as the original, you need to use something like a
UpdateRequestProcessor, which I personally am less familiar with.
