Here is my predicament.

Our staff handbook is broken down alphabetically per category and listed on a web page using an auto-directory-listing script from all files in a folder. The problem lies with people using different terminology and not being able to locate the correct document .
For example, a staff members looking for the staff absence document might look for a document called "Absence", "Sickness" or "Illness".

My headteacher wants me to abandon my ultra-easy auto-directory-listing script and develop a web page containing static links of all possible search terms linking to the correct document (ie - multiple links to one document). I have tried to explain how difficult it will be to maintain this type of structure but she is insistant that her way is easier for the majority of people so its the one that must be used, unless I can find a better solution...

What I would really like is to find a script where document links can be held in a database and search terms can be tagged to a particular document. I imagine that the front-end interface would offer a document list with additional search field, and on submission, would flag up a list of hyperlinks to all documents with that particular tagged word(s)

Does anyone know of a suitable script please?
