I need to join these together to see how many different cs_User_Agent strings the users had during the period and count those.
Basically to see how many of the users change/update browsers very often.
So, my result should look like this:
Number of UA Strings in the period | Number of Users in grouping
The results for search 1 & 2 would return A LOT of data, and from reading the subsearch info it sounds like that's not ideal as the whole subsearch would have to stay in RAM? Is there a better way than subsearch to do this?
