Variable in eval for URL

[bdfurman]

I'm sure this is fairly simple to do, just can't seem to find the right way to do this.

Let's say that I have a search string that returns multiple fields. Of those fields, we have:
foo: 100
bar: 200

Now I want to add an eval so that it will show "http://google.com/100/200". Essentially, I'm trying to tell it to do "http://google.com/$foo/$bar". http://google.com is nowhere in my search results, I am statically defining that.

How can i do that via eval? I would think I can do something like the following, but it doesnt seem to work.

| eval url=http://google.com/"$foo$"/"$bar"/
| table url

Try like this (dot as concatenation operator, fields can be referred directory by name)

your current search | eval url="http://www.google.com/".foo."/".bar."/"

Try ... | eval url="http://google.com/".foo."/".bar | ....
