Using Regex to match a whole string starting and endign with a word

I am trying to match a whole string using Regular Expressions. Despite reading lots of posts I can't work out just how to do it.

Is that right? Is there a more efficient way?

Thanks in advance for any help. I am a regex newbie and pulling my hair out!

Normal string functions are generally better for this: find the offset of "brown", find the offset of "lazy" after it, and grab everything in between them.

But in terms of regular expressions, yeah that's basically it. You might want the parentheses in a different spot and maybe a space between the words:

Without disagreeing with requinix, I'd also suggest you consider a small tweak:

brown.*?lazy
The question mark after the star ensures that you only match characters between brown and the first lazy (if you had several), as in:
That brown snake is a lazy snake, if I ever saw a lazy snake.
Without the question mark, the regex matches:
That brown snake is a lazy snake, if I ever saw a lazy snake.

Many thanks for the advice. I tested those and they work perfectly in the online regex tester, they don't work for WP-o-matic. It matches the whole article

WP-o-matic is a great tool but it doesnt do what it should with regular expressions.
