How do you find all files with two separate words?

Question

In VS2010, what would be the regular expression for 'Find in Files' to search for all source files that contain two separate words regardless of line breaks?

For Example I want to find any source file that contains 'This' and 'That'.

I tried something like this but it did not work:

((This).* \n* .*(That))

Answer 1

I find it easier to just do this, eg:

select|insert|update|delete

Note: VS's search needs to be set to use regular expressions. The order of the words does not matter.

So, we end up with something like this:

EDIT: To find a list, just do "Entire Solution", and then "Find all".
