Google Live Search Hints Script

[Tech Manager]

I am looking for a good "Google Live Search Hints" type scripts using Ajax, jquery, PHP, xml, MySQL:

Need the script to produce hints as people are typing in the search field.

The search must be able to pull data from either XML or MySQL. If searchingXML, the script must have the ability to limit the result set to a specific number of results, based on the query not the entire xml document.

XML format will look something like this:

<products>
  <product>
       <title>XYZ-123 Thingamajig</title>
       <url>some url</url>
       <image>some image</image>
  </product>
</products>

...and then be able to separate the product title (XYZ-123) and description (Thingamajig) for display in distinct div tags.

or be able to search on multiple fields (search tends to run much slower)

<products>
  <product>
      <title>XYZ-123</title>
      <description>Thingamajig</description>
      <image>some image</image>
      <url>some url</url>
  </product>
</products>

Thanks in advance for your help.
