regex - Regular Expressions: Is there an AND operator? -

obviously, can use | (pipe?) represent or, there way represent and well?

specifically, i'd match paragraphs of text contain of phrase, in no particular order.

use non-consuming regular expression.

the typical (i.e. perl/java) notation is:

(?=expr)

this means "match expr after continue matching @ original match-point."

you can many of these want, , "and." example:

(?=match expression)(?=match too)(?=oh, , this)

you can add capture groups inside non-consuming expressions if need save of data therein.
