Question

basically have two questions.
1. Is there a c++ library that would do full text boolean search just like in mysql. E.g.,
Let s say I have:

string text = "this is my phrase keywords test with boolean query."; 
string booleanQuery = ""my phrase" boolean -test -"keywords test" OR ";
       booleanQuery += ""boolean search" -mysql -sql -java -php"b

//where quotes ("") contain phrases, (-) is NOT keyword and OR is logical OR.

If answer to first is no, then;
2. Is it possible to search a phrase in text. e.g.,


string text =//same as previous
string keyword = ""my phrase"";

//here what s the best way to search for my phrase in the text?

Answer 1

TR1 has a regex class (derived from Boost::regex). It s not quite like you ve used above, but reasonably close. Boost::phoenix and Boost::Spirit also provide similar capabilities, but for a first attempt the Boost/TR1 regex class is probably a better choice.

Answer 2

As to the 2nd point: string class does have a method find, see http://www.cppreference.com/wiki/string/find

Answer 3

Sure there is, try Spirit:
