This PR was merged into the 5.3 branch. Discussion ---------- Moving RexExp search to its own heading See symfony/symfony#45032 (comment) I wanted to create a heading ("Search Using a Regular Expression") for this. Is `~~~~` the lowest level already? If yes, I'd suggest to drop the "Method Reference" heading, and promote all included "Methods to..." headings one level.
