Using awk instead of grep -f

Hi Guys.
I am trying to count occurances of patterns(occurance can be anywhere in file2) from file1 in file2.
file1 is
Code:
god
god
pod 
rod
file2 is
iamgod
iamgod
podrod
123rod456

output should be
Code:
god 2
god 2
pod 1
rod 2

I am not good at awk but i figured out this command.it doesnt give me desired output.
Code:
awk -F "god" '{s+=(NF-1)} END {print s}' file2

Can someone help please.
Thank you
Sam

i also have this awk script but its not giving me desired output
Code:
#!/usr/bin/awk -f
FNR==NR {
  f2[$0]
  next
}
{
  for(i in f2) {
    if($0 ~ (i))
      beg[i]++
    if($0 ~ (i"$")) {
      end[i]++
  }
}
}
END {
    print "anywhere"
    for(i in f2)
       print i,beg[i]+0
}

Would this come close?
Code:
grep -offile1 file2 | sort | uniq -c
      2 god
      1 pod
      2 rod

Hoppla - didn't take your thread title into account. Try this awk:
Code:
awk '
FNR==NR {OUT[NR] = $1
         CNT[$1]
         MX = NR
         next
        }
        {for (c in CNT) if (match ($0, c)) CNT[c]++
        }
END     {for (i=1; i<=MX; i++) print OUT[i], CNT[OUT[i]]
        }
' file[12]
god 2
god 2
pod 1
rod 2
