You have a very good point, alas. My hope was that in the general
case of a simple "return all matches" you wouldn't need to hit the
word database at all. I think we'll need to consult with Loic about
good ways to walk a list of words rather than generating the whole
list on-the-fly. I certainly don't have the memory for creating a
record for every word in my database. :-)
