How do I look for the existence of one field within another field?

For example, if I have a proxy log, and it shows User=A, then In the URL field we have "http://somesite.com/parameter=A", I want it to be able to pull up those logs.

You can make that comparison by using where like() in this way:

| where like(URL, "%".user."%")

Here's some sample run-anywhere code. Everything before the where like() line is just making a couple of test events:

| makeresults 
| eval user="Alex", URL="http://somesite.com/parameter=Alex" 
| append 
    [| makeresults 
    | eval user="Beth", URL="http://somesite.com/parameter=Baloney"] 
| where like(URL, "%".user."%")

Note that the % are being appended to the start and end of the user field for the comparison, because these are the wildcards for the like function.
