Although boost::split indeed takes a predicate that operates on characters, there's a boost string algorithm that can split on substrings:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
int main()
{
    std::string input = "message1foomessage2foomessage3";

    std::vector v;
    iter_split(v, input, boost::algorithm::first_finder("foo"));

    copy(v.begin(), v.end(), std::ostream_iterator(std::cout, " "));
    std::cout << '\n';
}
