I am writing a help file for a product and I need the help file to be searchable.
The help file can be HTML, PDF, DOC, etc., but I need a way to search, list and bring the user to the relevant page. I am going to be writing many tiny pages, snippets and variations of other snippets; Essentially just a lot of text to make the help file searchable and useful.
I haven't seen any help file that works well. As in: I can ask it a question and it will bring up relevant results.
What program/product can I use to make a searchable help file? The solution must work on Windows, Mac and Linux.
