Semantic searches can get a little tricky. We misspell things (we’re not perfect!), we create nicknames and abbreviations, we have rhetorical devices like metonymy and metaphor… why should we be constrained to just one keyword? What if you want to search for your brand’s mentions and your brand’s twitter handle?
Introducing (the implementation of) OR. Now you can search for multiple terms that relate to your keyword search. Just separate your keywords by or and all of the search results will live in the same place. Simple.
