Yes it won't work in that case. Because our matching criteria as $0 itself won't work here.

As per our matching pattern we can have arrays. Assume column 1 and 2 from file1.txt and column 2 and 5 from reference.txt. and print file1.txt.
Then we can use sth like this..

Code:
awk 'NR==FNR{A[$2,$5]=$0; next}{print A[$1,$2]?$0 FS "available" : $0 FS "not available" }' reference.txt file1.txt

Hope this helps you
