Glad that everything worked for you -- I've never tested the script using joins in the query, but I couldn't think of any reason it would be a problem.

The reason i have to do it is because to limit the db growth i have a location db with country and in the properies field i add just the location ID instead of the name…

Which is very sensible! Glad that everything worked for you — I’ve never tested the script using joins in the query, but I couldn’t think of any reason it would be a problem.

What i did was: in config.php i added an additional field for db_table, and on Search.php i just changed a bit the select string: AS relevance FROM $db_table LEFT JOIN $db_table2 on properties.location=locations.id WHERE... The reason i have to do it is because to limit the db growth i have a location db with country and in the properies field i add just the location ID instead of the name... So i wanted that the country name should be searched too.. Thanks for your great job! hi,

So i wanted that the country name should be searched too..

Thanks for your great job!

Hard to wrap your head around how to plan for who-knows-how-many different possible database designs. Regardless, as long as you're creating a valid database query and the resulting fields are defined consistently with your configuration file, you shouldn't have any problems. You might end up with some complications concerning which fields on which tables you're searching, of course -- it's entirely likely you'll end up needing to toss the configuration variable and hard code the queries. Depends on what you need.

Thanks for stopping by, Chiara! It was one of those checklists which just spurred me to actually <em>implement</em> what I should have done the first time around.

I rather like the total absurdity of the extremism in the expanded poem. Your original version, however, does take the cake for elegance -- the longer version becomes very difficult to scan due to the differences of meter and slant-wise homonyms. Thanks for stopping by!

I hope you find that your script is more usable now. And that is a great poem on the dangers of spell checkers. Ha! I’m so glad that you found the checklist helpful.

In 1992, I worked for AT&T and at the time we were proud of our proprietary e-mail. However, a debate raged over including or not including a spell check in the software. Lot's of arguments were forwarded on the topic ranging from "customers that can't spell shouldn't use e-mail" to limitations for computers with 64k of RAM. The argument spilled over into the daily e-mail blurb sent to everyone. I sent these two verses, which were published the next day, ending the discussion. My intention was to subtly lower the arguments to absurdity : I have a spelling checker It came with my PC It highlights for my review Mistakes I cannot sea. I ran this poem thru it I'm sure your pleased to no Its letter perfect in it's weigh My checker told me sew. A couple of years later I was doing a presentation on search engines and so began an urban ledgend.
