Re: Newbie: Searching with html form parameters
Nina: I didn't see a reply to your post. I'm relatively new to Cocoon but can relate to your question and was considering this tonight. Yes, if you're new to this environment it's going to be intimidating to figure this out since yes, it's straightforward to do ith with a relational db and servlet (I've done this). Most of the experts on this board will probably tell you it's easy to do this in Cocoon but of course they know how to do it. What they mean is it can be done with a few lines of code! There's a difference between easy and short. Technically, I believe the answer entails a pipeline that scours the directory for the file names, converting these to XML; next step in the pipeline scours each file and extracts JUST the street element; next step does the searching. That's the highlevel approach. You'll have to spend a couple of hours learning what a pipeline is and matchers. If you have thousands of files then for performance reasons you'd probably want to batch (daily, hourly, whatever depending upon the currency you need) the process of the first two steps above, and put the results into a file that would look like this: mydocs file name=foo1.xml street=elm/ file name=foo2.xml street=maple/ ... /mydocs then you would only have to search this file each time. This is just my thinking, from limited experience, but thought I'd put my two cents in. Like most things in Cocoon, seems there are numerous solutions to each problem. (I would have posted this to get others' feedback but I'm in the midst of moving my list subscription to another email address so it was difficult to do that.)

Hmm, doing this with XIndice might be straight forward too, as you only have to translate all the request parameters into an XPath. There are XIndice samples in the xmldb block.
