Answer by warren for Splunk equivalent to chained greps for searching within a search

Depending on your use case, you either do something like this:

index=ndx sourcetype=srctp fieldA=something fieldB=pattern fieldC=*

Or you might end up doing this:

index=ndx sourcetype=srctp "some literal text"
| rex field=_raw "a pattern of stuff (?<fieldtoextract>regex-goes-here)"

Or possibly this:

index=ndx sourcetype=srctp fieldA=*
| stats values(fieldB) by fieldA
| where mvcount(fieldB)>3 AND match(fieldA,"something")

Or maybe something else entirely.

If you have sample data, we can help craft some more-specific SPL for you – but there are many many many ways to "search within a search" in Splunk.
