Search in Mysql with FULLTEXT IN BOOLEAN MODE including keyword operators?

Question

How to make in BD Mysql, in an Innodb table with two fields indexed by FULLTEXT, a search is performed through the MATCH query (column1, column2) AGAINST('keyword' IN BOOLEAN MODE) including even the operators that are in the word to be searched?

Understand:

SELECT * FROM languages WHERE MATCH (title, body) AGAINST ('C++' IN BOOLEAN MODE);

Remembering that the sign of + is one of the operators that can be used in the word to be searched IN BOOLEAN MODE, as -, <, >, @, among others to obtain more extended results.

Therefore, the query of our above example fails, due to the word being C++, which is actually interpreted as a letter followed by two operators (C++).

I would like the search to ignore the operators but to perform the search with them IN BOOLEAN MODE, can not be IN NATURAL LANGUAGE, unless the natural language mode can bring even the 50% that are discarded from the search, that is, bring the result with all existing values as in boolean mode, without ignoring words that are too repetitive.

To complete the information and who knows how to elucidate other new ways to resolve the issue, the programming language that will implement the research process will be PHP and the word that should be searched will be loaded into a variable via POST (AJAX) after completing the user search field. Any other path that leads to the same result is also welcome!
