| MODULE NOTES:
| -------------
|
| I've been deliberating whether we should implement some kind of WORD ID /
| search logging table for index.
| iB3 PERL had such a feature, but that was to aide the DBM searches, which
| were slow at best.
| The biggest complaint we had was that adding a word ID / search logging table
| effectively doubled the amount of space needed in the mySQL database. I've seen
| this complaint echo'd on the support boards of other forum software.
| The other downside to such a feature would be the overhaul needed to update it
| with new posts/topics and topic movement / deletion.
|
| I figure that people post more than they search, so a full table scan once per
| search request is offset against the CPU to keep the search log tables up to date
|
| I'm going to stick my neck out and go the full table scan route. It's not as effecient
| as a search table would be, but the benefits include no overhead updating it, and a smaller
| overall DB size - which is vital to some people on certain hosts.
|
| This may change if it becomes apparent that it's not very efficient in the long run

// To find the maximum records that match our criteria to
