I believe such uses are fundamental pieces of IR, so it shouldn't be surprising that IR tools can do this, however, we have to actually make something SQL or something IR do it in finite time...(both developer time and wallclock time...)

Never meant anything similar. No no, I didn't interpret it that way, I may have been unclear. I just want to make sure do eventually build things that provide what Tibor described. But additionally I didn't want to skirt around Tibor's example by saying that it might overload the DB. I really would like to know whether that use could be delivered in Lucene in acceptable speed, because it seems like its a nice, but practical and relevant, test of what an IR tool might be doing in our context. I'd still like to know whether this case is better with Lucene or MySQL, as that helps me understand where the boundaries should naturally live.
