I'm playing with regular expressions and would like to be able to use a and operator in a single search item for example all documents that contain the word "happy" and "dog". I have tried this syntax (?=.happy) (?=.dog) but it doesn't work. I know it is possible to use the And operator in the text search but being able to use regular expression would mean we can create and save one complicated search query rather than have to build multiple queries.
