Using keywords for filtering like hashtags

Hi,

I creating a list of names and each name (row) has at least 3 keywords as in the table below.
#

Name	XXX	Kewords
A	AA	C, D, E
B	BB	C, F, G

now I would like to write a function that allows each user to search a maximum of 2 keywords and see which names have those keywords.
example:
let's say the user wants to search keyword C, the answer would be: names A and B. Then the user searches keyword E and the answer would be: name A.

I would appreciate it if anyone would help me with this.
