This search only searches for a set of log messages that contains TCP protocol, info field value that contains syn, the same dest field value and eventcount >= 20 (for 20 consecutive log messages). How do i change this search expression that includes checking if any messages that contains log messages that contains TCP protocol, same dest field and info field value contains FIN and ACK such that splunk produce the same result.

protocol="TCP" |where match(info, "SYN") |transaction dest |search eventcount>=20

try something like:

protocol="TCP" | transaction maxpause=1m dest | search info="SYN" info="FIN" info="ACK"

the transaction will create a multivalue field on info, so the seach above makes more sense.
