Give visual LS feedback and pause on multiple words

[Paul Everitt]

We have a performance problem we'd like to solve with a usability fix.

On performance, if you do a LiveSearch for:

  paul e

We issue a search for paul AND e* as the query. The latter is the performance killer we put the throttle in for on KARL3 (it wakes up 100k catalog objects.)

The usability fix is that, if you type:

  pa

...you get no visual feedback. Here is our proposed solution, in JS, to both of these problems:

1) If you are typing a word and only have 1 or 2 characters, display the full-height drop-down, with a <div> at the top as a notice:

  (i) You must type 3 or more letters in a word to get suggested matches.

...where the (i) is the symbol we use on an information message such as status_message.

2) If you have typed one complete word and have some matches currently displayed, keep those matches, but put the notice message at the top.

3) Equally important, don't issue a new request until the word has enough letters.
