I found the following [SO question from 2015](https://stackoverflow.com/questions/31245663/combine-match-with-or-clause-in-the-where-statement), which indicates that FTS3 had a similar bug once, but unfortunately the [linked mail list archive](http://sqlite.1065341.n5.nabble.com/FTS3-bug-with-MATCH-plus-OR-td50714.html) is not available anymore.
