c++ search text n boolean mode
basically have two questions.
1. Is there a c++ library that would do full text bo开发者_运维百科olean 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?
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.
As to the 2nd point: string
class does have a method find
, see http://www.cppreference.com/wiki/string/find
Sure there is, try Spirit:
