My testing result
Code:
$ cat a
cool:niceone
revoke
similar
jeep
34343
34343


cool:notone
aefdfdd
sdsdsds
sdsdsds
sdsdsd
sdsds

cool:unknown
xxx
yyyyy

cool:city
123
456
$ cat b
city
niceone
$ cat raghav.sh
awk '
   NR==FNR {
      keys["cool:" $0]++;
      next;
   }
   /^cool:/ {
      display = ($0 in keys ? 1 : 0);
   }
   display
    ' b a
$ raghav.sh
cool:niceone
revoke
similar
jeep
34343
34343


cool:city
123
456
$

Trailing spaces in records from files a or b may cause problems.
Try the following version:
Code:
awk '
   { gsub(/[[:space:]]*/, "") } # Removes trailing spaces from record
   NR==FNR {
      keys["cool:" $0]++;
      next;
   }
   /^cool:/ {
      display = ($0 in keys ? 1 : 0);
   }
   display
    ' b a

Thankyou!!

Your requirement is a little bit different as the original.
In the original data file a, the was no space after the seached string(cool: ), and no other texte after the the seached keyword string.

Try the following script :
Code:
awk '
   NR==FNR {
      keys[$1]++;
      next;
   }
   /^\/\* -+[[:space:]]*.*[[:space:]]*-+ \*\/[[:space:]]*$/ {
      k = $0;
      gsub(/^\/\* --*[[:space:]]*|[[:space:]]*--* \*\/[[:space:]]*$/, "", k)
      display = (k in keys ? 1 : 0);
   }
   display
    ' b a
