According to glibc,

#if SHLIB_COMPAT(libresolv, GLIBC_2_0, GLIBC_2_2)
# undef res_mkquery
# undef res_query
# undef res_querydomain
# undef res_search
weak_alias (__res_mkquery, res_mkquery);
weak_alias (__res_query, res_query);
weak_alias (__res_querydomain, res_querydomain);
weak_alias (__res_search, res_search);
#endif

i.e. "res_search" is only available if the oldest version of glibc for
that platform was 2.0.x, I believe.

Whether this is standards conforming or not you'll have to take up with
someone who knows POSIX better.
