Hi, Ian,

What you're trying to do is much more sophisticated than what is being done by the code I sent you. I worked on an application a couple years ago with similar requirements for searching for pictures. In order to meet those requirements, we integrated Gary Teter's WireHose frameworks and, using them, created an index of pictures with keywords for each picture.

     http://www.wirehose.com/

Wirehose is offered for free and has some sophisticated searching and indexing built in that, if you use, could save you a few weeks of programming. Your end result would probably have a higher quality as well, since Teter's code has gone through a few generations of optimization by one of the WO masters.

I hope you've provided some lengthy estimates to your users, because this is not a quickly solved problem. Searching is an inherently difficult problem space.

Regards,
Jerry

Hi Jerry,

Thanks very much for your thorough reply. I'm going to have a play around
and see if I can get it to do something in my app. I gather that the code
would try queries from more than one field. I was sort of intending
something similar to that, but where a single query is run through a
number of options for each entry. i.e. when you add the entry in the first
place, you might know that you should enter "hard drive" and "hard disk"
so that if someone is searching for "hard drive" it would find the entry
just as if someone had searched for "hard disk" the same entry would be
retrieved. But this should all happen without the user (who is doing the
searching) needing to give it a second thought.


Ian.

Hi, Ian,


If I understand your question correctly, you want to be able to do a
fetch using something like "Get myRecord where searchfield is 'Smith' or
'Smythe', or ...", then you can use an EOOrQualifier.
