Looking at this I'm not sure what this is good for.

Why would we want to match strings of the form _xxx at xxx
in a full-text indexer?

Perhaps it would be best to get rid of the whole messy
regex (of which this is only a small part) and write
a new documented one from scratch. Or use a custom
state-based tokenizer.
