Just surround the topic with quotes:

?">"

and 

?"%in%"


This is covered in ?help:

"Some topics need to be quoted (by backticks) or given as a character string. There include those which cannot syntactically appear on their own such as unary and binary operators, function and control-flow reserved words (including if, elsefor, in, repeat, while, break and next. The other reserved words can be used as if they were names, for example TRUE, NA and Inf."

HTH.
