There isn't a quick and easy way to make this perform better / be more efficient. Splunk's use of boolean AND/OR/NOT is generally very efficient up until you have several thousand terms in your search.
Syntactically, though, you may want something to sweeten it. Folks have brought up before the concept of field IN (aaa,bbb,ccc) as syntactic sugar around OR. This doesn't exist though.
If your list of items is LONG (tens / hundreds) you can make a CSV file and use a lookup, say called measInfoId.csv like so:
And then use the inputlookup command to drag it in. It produces the same long list of OR statements just without putting your "O" and "R" keys through such a workout.
