When searching some documents, I notice I can't search full sentences if there is a line break. It works normally on Chrome's native PDF reader. In some documents the search works, but it won't work in others.
Just as a sidenote, I tested with a bunch of pdf readers and some could find it (foxit) and other couldn't (evince, atril, xpdf, firefox's).
Above, comparison of chrome's and okular's search, respectively.

In Chrome it works as intented

In Okular it wont work if I try to search for the whole sentence, showing no results
