1. Have a Qt version with documentation in PATH.
2. Start Creator with empty settings, e.g. by passing the parameter -settingspath <empty directory>
3. Go to "Tools" -> "Options..." -> "Help" -> "Documentation".
   Creator lists the documentation files from the Qt version in PATH.
4. Remove all files except for the one containing "qtcore".
   Be careful not to run into QTCREATORBUG-16747.
5. Go to Help mode.
6. Open the Search view.
7. Open the Advanced search.
8. In "with all of the words", type "deploy" and press Enter.
   One result is being found.
9. In "with at least one of the words", type "Palimmpalimm" and press Enter.
   The same result is still being found. Do I need to say that this page does not contain the word "Palimmpalimm"?

That page should not be found since it does not contain a required word.
