Which to use "Search_Highlight" or "Search Highlighting"

Hi,

I’ve just upgraded my old rc2 to rc3.

Now, prior to this upgrade, I tried to update the AjaxSearch to v1.6. I followed the instructions to upgrade that, and created a copy of the "Search Highlighting" plugin called "Search_Highlight" (as this is what the doc says to do).

Which should it be? I’m assuming I can remove the Search_Highlight version?

Also, why does the version of the snippet in the 1.6 archve state v1.5 and the version in rc3 state v1.6? I confused.

Thanks,
Luke.
