Hi Sohail, Hashed indices will be available in 1.33 (due to be released in a matter of days). boost-consulting.com/boost shows the documentation as in the current CVS, so what you're seeing is really a preview of the release to come. The official docs are at boost.org. Regards, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Is this a new feature (http://boost-consulting.com/boost/libs/multi_index/doc/reference/index. html)? I don't seem to have it in my 1.3.2 installation. Thanks Sohail _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
