WP Live Search (beta) is a search plugin for WordPress that returns results as the user types for what they are looking. It currently supports posts, pages, post types, including multiple post types, and design modes.
This is very much a working prototype, so please log any issues you find on the Github repo below.

Add the shortcode <code>[wp_live_search]</code> to a page or something. There’s a few shortcode attributes that you can use, and are as follows:
type=”” 
Your choices are <code>posts</code> or <code>pages</code>. Defaults to <code>posts</code>. You can also pass <code>type,type</code> to search multiple post types. For example type=”recipes,books”
multi=”” 
By default this is turned off. Set this to true only if you’re using multiple post types above.
placeholder=”” 
The text displayed in the input. Defaults to <code>Search...</code>.
number=”” 
Total search result to return. Default is 20
excerpt=”true” 
Show the excerpt along with the title and featured image (if set)
compact=”true” 
Makes a tiny WP Live Search for use in header widgets and such
dropdown=”true” 
Display search results as a drop-down instead of pushing down the content around it
results=”” 
The text displayed for the results. Defaults to <code>entries found</code>.
results_style=”inside” 
Displays the “entries found” inside of the input area, useful for using in areas like header widgets where space is minimal.
target=”” 
An optional target UL parent to send the search results to. Example <code>target="#someotherdiv"</code>.
Here are a couple examples:
Default Usage:
