App to dynamically sort information by keywords sought

sladuuch

I have a huge document, composed entirely of bullet points about specific applications. So far, the document is organized by application--e.g. the "iTunes" section contains info about iTunes, the "TextEdit" one contains info about TextEdit, etc.



My question is this: is there any applications out there that will allow me to tag entries with keywords so I won't have to organize the document myself? Ideally, what I'd like to do is write en entry, then assign keywords for that entry for which application the data pertains to, as well as the specific thing I'm talking about, and then be able to sort by different criteria; say, all entries about interfaces, all entries about inspectors, all entries about security, etc, and the document would update to display this change.



Anything out there that can do this? Sorry if I've explained it in a roundabout way.

For one document, this sounds like something any spreadsheet or database app will be able to do. For a spreadsheet, you can display only those rows with a certain value ("inspector") in a certain column ("keyword"). For a database, you can choose to display only those records with a certain value in a certain field. I am misunderstanding the complexity of what you want to do?
