I have some documents contains c# or c++ in title which use standard analyzer. When I query c# on title field, I got all c# and C++ documents, and c++ documents even have higher score than c# document. That makes sense, since both '#' and '++' are removed from token by standard analyzer, so both C# and C++ are converted to 'C' in inverse index table.
Then what is the best way to handle this kind special terms? In my case specifically, I want c# documents got higher score than c++ documents when searching for "C#".
