What is the disadvantage of doing that?
Besides being a bit awkward, it could use more RAM and time to compile
queries. That could be because a query like "foo*" gets expanded into all the
terms from the index that begin with "foo", ORed together, like so:
"foo" OR "food" OR "fool" OR "foot" ...
I suppose it's theoretically possible that if you have millions of unique
terms that all begin with the same thing and then use that common prefix as a
query, you could notice. I haven't noticed anything at all in my application,
which has a few million documents and ~10 million unique terms.
In other words, in practical situations I doubt there are any disadvantages.
