Is there any additional advanced search operators that would enforce the existence of
[=1] in search results? Using double quote
"[=1]" does not work. I couldn't find relevant info in https://stackoverflow.com/help/searching
In particular, I'm looking to search in http://tex.stackexchange.com where such argument can show up in the code.
This particular expression currently cannot be searched with Google nor Bing advanced search operators.
