Multiline regular expression search in Visual Studio Code
Multiline regular expression search doesn't work in VS Code version 1.27.2 .
Theoretically aaa(\n|.)*bbb should find string starting from aaa and ending bbb but it doesn't work.
The solution mentioned here Multi-line regular expressions in Visual Studio Code doesn't work as well.
Answer
Multiline search is added in v1.29 released in November 2018. See multi-line search.
VS Code now supports multiline search! Same as in the editor, a regex search executes in multiline mode only if it contains a \n literal. The Search view shows a hint next to each multiline match, with the number of additional match lines.
This feature is possible thanks to the work done in the ripgrep tool to implement multiline search.
Multiline search is coming to the Find Widget with v1.38. See multiline find "pre-release" notes.
Multi Line search in Find Widget
The Find Widget now supports multiple line text search and replace. By pressing
Ctrl+Enter, you can insert new lines into the input box.

Odd that it is Ctrl+Enter in the Find Widget but Shift+Enter in the Search Panel (see Deepu's answer below). Shift+Enter has other functionality when the Find Widget is focused.
