Re: dot to be considered as a word delimiter?

Fair enough. I agree that there is a valid need for returning such tokens as
a host. But I think there is definitely a need to break it down into
individual words. This will help in cases when a document is missing a space
in between the words.

So what we can do is: return the entire compound word as Host and also break
it down into individual words. I can put up a patch for this if you guys
agree.

Returning multiple tokens for the same word is a feature of the text search
parser as explained in the documentation here:

Thanks,
Sushant.
