C-h f skeleton-insert RET says:

   Quoted Lisp expressions are evaluated for their side-effects.
   Other Lisp expressions are evaluated and the value treated as above.

so you can use '(search-forward ...) in your skeleton to tell skeleton
that the return value should be ignored.
Otherwise, you can also use (ignore (search-forward ...)) since `ignore'
always returns nil.
