When searching in Workfront, on the Community site, or on the Experience site/Idea Exchange, you should be able to use quotation marks around words that must be in the title/description of objects you're searching.
For example, I should be able to type the following:
"language" different in 2 different "browsers"
which would tell the search engine that all results returned need to contain one of both of the words language and browser. It should also work for strings of words.
The search functionality all across Workfront isn't robust enough and too many times, results are returned to me that have nothing to do with what I searched.
