Adding and populating a field

[Keith Rhodes <kr...@yahoo.com>]

I have a set of documents with filenames that give a good indication of content.

A filename of 12 digits (I think this is [0-9]{12} as a regular expression) with the extension html is a troubleshooting guide, the number being an error code.
A filename with two or three letters, then a minus (which would be [a-z]{2,3}- I think), then a known string means the document is about a particular subject; I have a list of the known strings matched to subjects.

What I would like to do, is have my indexer create a field named "category", populated with either the string "troubleshooting" or with the known string extracted from the filename.

Examples:
For a file named 0000000000111.html the indexer adds the field "category" with the value "troubleshooting".
For a file named xxx-cal-123.html the indexer adds the field "category" with the value "cal".
For a file named xx-qv-(9).html the indexer adds the field "category" with the value "qv".

Is there a way to do that?

no automatic way, you to do it yourself. Presumably, you have
some master list of categories that you can map your file
names to, so as you index each file you have to look up the
category and add it to the document you are about to index.
