Newbie: find, search command

[D.Rothe]

Hi,
I have a tab delimited list I want to be able to search, say I have a list of names for example;

Father Xmas    Is Drunk
New Years    Is after Xmas
Rudolph    The Reindeer
Merry Xmas    To all

I want to search for ALL instances of Xmas and display the whole matching line of each found in a list field.
So far I can get it to display the first line only ( Father Xmas    Is Drunk) ! 
Any help would appreciated!!! I have checked the tutorials for help but couldn't find what I was looking for,
is there an example stack or notes anyone may know of?

Thanks D.Rothe
