Hi Michael,
You might also be interested in some of the words in "sequences" which
handle this particular use-case. For example, see "find", "find-from", and
"find-last".
( scratchpad ) { "bread" "eggs" "milk" } [ "eggs" = ] find
--- Data stack:
1
"eggs"
If you're curious how it is implemented, you can type: "\ find see" and then
click on different parts of the word definition to see its implementation.
Best,
John.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
