Here's a modified version of your code that uses registers and returns index of match.

Function un.StrContains ;returns -1 if not found, idx if found

Exch $R0 ; searchFor (Needle)
Exch
Exch $R1 ; searchIn (Haystack)
Push $R2 ; return var
Push $R3 ; idx
Push $R4 ; needle length
Push $R5 ; substr @ idx
Push $R6 ; haystack length

StrCpy $R2 "" ; reset ret
StrCpy $R3 -1 ; var1 = -1
StrLen $R4 $R0 ; var2 = needle length
StrLen $R6 $R1 ; var4 = haystack length

loop:
IntOp $R3 $R3 + 1 ; idx ++
StrCpy $R5 $R1 $R4 $R3 ; substr = haystack.substring(idx, needle.length
StrCmp $R5 $R0 found ; if (substr == needle) -> found
StrCmp $R3 $R6 done ; if (idx == haystack.length -> done
Goto loop
done:
StrCpy $R3 -1
found:
StrCpy $R0 $R3

Pop $R6
Pop $R5
Pop $R4
Pop $R3

Pop $R1
