IOW it is context-dependant.

Hence I implemented the three thresholds for
phrase-boundary, word-boundary, and instring matching.

> We don't think substrings, e.g if I want ranitidine,
In that case the programmer sets:

phrase threshold = 2
    - so "ra" -> "ra*"
word threshold = 3
    - so "ran" -> "ranitidine Hexal" and "Roche Ranitidine"
instring threshold = 128
    - i.e. it never happens, not even when editing

> I dont type in 'tid', or 
Unless you wanted to pull up the "*tid*"ines and you were
wondering if there's anything else besides Ranitidine and
Cimetidine ;-)

But you might type (especially as a less experienced
prescriber) "cilli" which would bring about Amoxicillines,
Pencillins, Benzyl-Penicillines and Infecto-Bicillin (a brand
name here).

This is a matter of personal taste/debate, though.

Sure !  Set the thresholds accordingly.

Sure, I was just trying to kill the usually available ASCII

I wouldn't write something like that but why not catch it if
we can ? The question is: Does it make sense to treat @ as a
word separator or should it rather be an ignored_char ?

Yes :-)

I have observed this @Chiang Mai University Medical School
where interns&residents liked 2b hip and use SMS talk in the
medical record for brevity. I do not think it is the job of
the phrase wheel to censor the way one expresses one's

It would already come up earlier, during the in-phrase
word-boundary search so that you can set the instr$ threshold
higher such as to not be bothered by undue instring matches.

Can you describe it in one of those excellent spec docs ?

Maybe it'd be useful to extract the generic phrase-wheel specs
into their own document ?
