The goal of the "web" tokenizer is to recognize web things like
- email addresses
- URLs
- twitter @handles and #hashtags
This implementation uses regexp exceptions. There will most
likely be endless debate about the regular expressions. These
were chosein as "good enough for now".
There is also a "web" analyzer. This is just the "standard"
analyzer, but using the "web" tokenizer instead of the "unicode"
one. NOTE: after processing the exceptions, it still falls back
to the standard "unicode" one.
For many users, you can simply set your mapping's default analyzer
to be "web".
