Use SLED 11 R2 (kernel 3.0.13). Try to locate a file containing certain character string.

For instance, a document named Test.doc contains the words "Find Me". My reasonable guess is this file may locate at /home/tester directory, but not sure. So I went to Tolls --> Find File. In the popup window, I types Find Me in the Contain Text in the Containing Text field. More often than not, I could not find the file Test.doc which indeed contains the words "Find Me" and is located at /home/tester.

Is there a third party search utility which could be more efficient and I can download somewhere?

(Back in Windows, there was a good tool named Agent Ransack. I just hope there is one for SUSE).
