I recall the discussion about
what range-algorithms should return.
My current answer is:

     std::string src("abcdefghijk");
     namespace ph = boost::phoenix; // version2
     {
         std::string s1("efg");
         BOOST_CHECK((
             equals(
                 std::string("efghijk"),
                 src|applied(ph::search(rng1, s1), end)
             )
         ));
     }

Users specify it by using lambda expression.
