I'd better apologize at the outset as I'm not sure this is strictly a PHP problem - though I'm using PHP as the means of building the application. Anyway, here goes:
I'm creating a website that will function as a directory of services within a specific area of the UK charity sector. A variety of groups will input the content via a custom built CMS and this content will then be available to the general public. One of the requirements is that a keyword search facility is built into the application allowing end users to search for services based on a variety of words they might associate with them. What I propose to do is have a separate table of keywords/phrases that have been previously entered by contributors. There will then be a separate table linking the id field of the associated keywords with the id field of the service in question. Herein lies the problem. The contributors will be presented with a multi-part form. When it comes to the stage at which they will need to enter the relevant keywords for a service there seem to me to two ways of dealing with this: 1. Allow the contributors to enter whatever keywords and phrases they wish. 2. Only allow contributors to have access to a restricted set of keywords/phrases. The first of these options would run the risk of creating an unmanageably large and devalued set of keywords/phrases. The second option would seem to result in a set of keywords that are too generalized to be of much benefit to the ultimate end users. Are there any accepted approaches to tackling such a problem which anyone could point me towards? I'm sure it must have been encountered before though I've been unable to find much on this after extensive googling and searching through mailing list archives.
