Matching strings in awk taking the input fro the text files

I want to ask a question regarding the strings matching in awk language. I have multiple strings in a file like :

abc
def
ghi
jkl
mno
.
.
.

I want to match these strings in the other text file.

Is there an easy way to do that using awk? Thanks for any help.

If string from 1st column of file1 has to matched to 4th column of another file2 and all the lines (matched only) are to printed. than i guess this is an easiest way to do in awk.

awk -F "field seperater" '{a[$1=1]} a[$4]' file1 file2.

Yes, there is an easy way of doing this in awk. 

awk 'FNR==NR{a[$0];next}($0 in a)' file_1 file_2

where file_1 is your string file and file_2 is your search file.
