I have a search form that queries various web sources for information (there is no db). I'm wondering if there are any tutorials or scripts that can accomplish the following:
Display related terms (if i search for 'car' - 'new cars,' 'car parts,' etc would show up as links to those related searches.)
Spell check terms (if someone types in 'truk' it will suggest 'Did you mean: truck?')
Anyone have any ideas?
