regex in lookup file

I want to match a reg ex pattern (e.g. "aaa\s+:\d\d") from a lookup file.

pattern,output_value
"aaa\s+:\d\d:", 2
"aaa\s+:\d:", 1

So, whenever first pattern matches in the event, I should get value as 2.
How can we do this?

Build a subsearch to build the EVALs for you?

| makeresults 
| eval _raw="aaa :4:" 
| eval 
    [| inputlookup test_regex.csv 
    | fields pattern output_value 
    | eval search="test=if(match(_raw,\"".pattern."\"),\"".output_value."\", test), " 
    | fields search 
    | mvcombine search 
    | eval search=trim(trim(mvjoin(search," "),"| eval"),", ")]
