Change the parameter you look for when the referrer is maps.google.*

[#1]

Currently, SiteCatalyst looks for the properly formatted "q=" when the referrer is "*.google.*".  We started seeing query strings added to the maps.google.* referrers.  They are using the "q=" to designate what Google Places link the user potentially was looking at.  They are using a "dq=" to designate the query that the user typed in.  We are seeing urls for our keywords when the referrer is maps.google.com.  This is not very helpful.  I would think you need to update your lookup table that has the known search engines along with their query parameters.
