[Boost-users] regex problem: removing two elements in a row?

I want to use boost::regex 1.33.1 and vc7.1 on a WinXp-Sp2 computer to 
remove common words from a file. I'm encountering a problem which 
seems related to having two of the common words next to each other.

std::string test(" in the beginning god created the heavens and the 
earth ");
boost::regex reg;
reg.assign("( and | can | did | the | in | a )");
test = boost::regex_replace(test, reg, "  ");
cout << test << endl;

The result is:
" the beginning god created  heavens  the earth "

Am I doing something wrong or leaving out a step? Seems like the above 
ought to work. It catches one of the occurrences of " the " between " 
created " and " heavens " but not those immediately after the " in " 
or " and ".
