Capture Filter for FRAMES

Hello,

I need to capture a frame lets call it "text".

For now I use a Display Filterthis way: Frame contains "text"

It works fine, BUT because it's just display filter Wireshark captures a lot in background. (Server 24/7)

So the problem is, filtering the results after a few hours take ages. It's not possible to work this way.

How can I use a CAPTURE FILTER for that "text" which ONLY captures the necessary stuff? Otherwise Wireshark dies during capturing because of so many captured data, which I don't need!

It's also not possible to use another kind of Capture Filter, because length, port and IP is always diff. The only constant thing is, that it's UDP protocol.

Some ideas?
