I'm trying to implement a kind of "search as you type" feature with the Search bar. Essentially, I'd like to have the user begin to type, make some kind of ajax request after each key, and then populate a div with "Related searches" as they type. Any good plugins for this or should I bake it up from scratch?
I have developed an ajax search plugin a few weeks ago. There is a free version available at the wordpress plugin repository. Feel free to explore the source code :)
You can find it here: Ajax Search Lite
There is also a commercial version, maybe you are interested: Ajax Search Pro
You can check out the demos and see if it fits your need. Also, I provide quick and free support if something goes wrong. Im not sure if this is what you are looking for, but I hope I could help.
