Processing Rules: Make Search Keywords variable available

[#1]

Currently Search Keyword is not available in processing rules as a variable. (probably because the processing that creates it is after the processing rules stage)

However, it would be really useful if Adobe could make this available for processing rules.

The only way to get at this in processing rules is to try and look for the referring URL query string parameter which is difficult because different search engines use different parameters :-(

This one is huge.  The main reason I'd say is that the current settings for the search keywords are rather lacking.  Putting this in an eVar will open up many more options.  It'd be nice to not have to do a hack to get this by using a processing rule (make the variable that captures this just like an eVar by default), or by using a VISTA rule or some JavaScript.
