[Boost-users] Question on data structure usage

Hi,

I have a map as follows,

boost::unordered_map<string, string> sample_map;

I would like to look up the keys using wildcards/regex from the user and
get the values corresponding to it(get multiple matches). It looked like
there is no straightforward way to do it.

So, I was thinking as an when I populate the map, I create a seperate data
structure to store the keys, so that I can get the values(list) that match
my user inputted regex/wildcard search. The I use this list to get the
values from the map.

What data structure can I use for this purpose? Is my approach correct? Or
can I do this directly using the map?

Please help me solve this problem.

Thanks,
