the OP may not need such fanciness.. it depends on the amount of reports he wants to store, the types of searches (if any) done by browsers, and the amount of searches to expect.
and the OP may not have good db design skills yet. for a noob, it's one timeconsuming thing to build a datamodel, but it's harder to get it efficient yet simple. if the oop wants to start a site with lots of reports and lots of searching, we'd even have to remind him of the cloud hosting option, which i'm sorry to say, has no real rdbms (mysql) support yet, and is not always paid by the minute (but by the hour), meaning it's got only a small chance of reducing his operating cost (by a lot); it's still worth investigating in this case (given the much easier scaling abilities of cloud hosting). OP: if you need a mysql datamodel for reports, i'm willing to give it a free shot. i'm sure others here would too, or improve upon mine. It's probably not more than 3 tables i think. Let us know eh..
