Finding 50k Keywords in 3k files

Hi,

I have a file with about 50k keywords. I have a requirement to scan about 3k files to identify which filename has which keyword i.e. an output like following:

File1,Keyword1
File1,Keyword2
File3,Keyword1
.....

I have written a shell script which takes each of the 3k files, searches for the existence of the Keyword one by one (using grep). Once it reaches the end it starts with the next file.

I would like to know if there is a more efficient way of carrying this operation out?

Thanks in advance for your help.
