Thank you for the answer, I see how this can limit my design and I
will code accordingly. Considering the fact that my users may
subscribe for alerts up to potentially thousands of words, I'll have
to add more subscriptions.

I'm not sure to fully understand the "number of matches x registered
subscriptions". Say, for example, that I have a million registered
subscriptions, but only 0,1% of them concentrate most of the match
calls. Wouldn't the formula you posted above make these almost-never-
used 99,9% remaining subscriptions make my prospective-search billing
quotas skyrocket ?

In other words, "idle/never matched" subscriptions would greatly
increase the cost of those of the most active subscriptions that are
matched on a regular basis. I picked exaggerated numbers on purpose,
though some applications may be designed that way (including mine,
hehe...).

I never realized before that pricing formulas could influence code/
application design that much.
