I think you will find that the whole point of a capture filter is to minimise the work needing to be done during capture time. As such their is minimal (even no ) functionality to search for arbitrary text.
As such I would suggest using tshark with a "-R" display filter using the "contains" or "matches"
keyword.as appropriate.

Users -
I
have been using Wireshark to capture test data. The Wireshark filter
is as follows:
ip.src=""
and (ip[0:] contains 00:00:87:00:00:00:18) or (ip[0:] contains 00:00:86:00:00:00:50)
The
desire is to parse all traffic by the Unit Under Test IP (10.10.2.1), then
finding a record payload that has either the 87 or 86 above (tells me fault
files).
Life
is great and working with Wireshark (nice tool!!!) but here is my problem...
I need to automate w/o a user intervention. I have a batch
file working but the Wireshark filter above is NOT a cut and paste for
the Command Prompt...:
"c:\program
files\wireshark\dumpcap.exe" -i 1 -f "src host 10.10.2.1 &&
(ip[51:1] = 134 || ip[51:1] = 135)" -a duration:60 -w C:\backup\Captures\PBIT_cap.txt
This
assumes that the 86/134 dec and 87/135 dec are in a fixed location....murphy
now shows it's ugly head and it is in different places in the payload of
the ethernet record. So I tried to get the "ip[0:] " working.
How do I do this as it seems not to allow dynamic searching during
capture??
Thanks,
