While one could do this, if the goal is to be a safety valve you might
this check to be enforced at the core Boolean level instead of by each
extension.

But my instinct would to figure out a way simply make the search work,
rather than throwing it out as an exception.  Supporting a search for
"a* lovelace" seems reasonable, and shouldn't actually be that
expensive if implemented lazily.

If one was to have a limit, it should probably be on the total length
of the records that need to be searched, not on the number of terms
involved.
