At the cost of some redundancy, you might be able to speed it up a
little bit by requiring that it start with at least one of the words
like

  /\%(\<\%(quick\|brown\|lazy\|jumps\)\>\)\@=\%(.\{-}quick\&.\{-}brown\&.\{-}lazy\&.\{-}jumps\)/

so it won't start looking for the other terms until it's found at
least one of them, cutting out a lot of non-starter cases.

That finds *any* of the words, not *all* of the words as the OP requested.

While the implementation can often end up slow if you have a large
text or lots of find-them-all terms, you (OP) can use

   :help /\&

to join the conditions like

    /.\{-}quick\&.\{-}brown\&.\{-}lazy\&.\{-}jumps/

-tim

Thank you; that's exactly what I was looking for. It does slow down, though, as you said it might, once I add more words to it. I might write something that does the combination thing I was suggesting and time the two approaches, but with more than just two words: /quick.*brown\|brown.*quick/ vs. /.\{-}quick\&.\{-}brown}/ 

Best regards,

Salman

Re: Finding all words

Hi,

I would use something like this:

\v<(quick|brown|lazy|jumps)>

\v - very magic

< - the beginning of a word

> - the end of a word

(quick|brown|lazy|jumps) - the words to find

Thanks,

Mikhail Velikikh

Hello,

Is there a way to compose a regular expression in Vim that will find all the words I want, irrespective of the order in which they occur? For example:

Some text...

The quick red fox jumps over the lazy brown dogs.

Some other text...

I want to find 'quick', 'brown', 'lazy' and 'jumps'. I don't know the order in which they occur, so something like 'quick.*brown.*lazy.*jumps' won't work. I'm trying to avoid a complicated/ugly expression that includes all possible orderings like '\%(brown.*lazy\)\|\%(lazy.*brown\)'.

I'm hoping there is a more graceful way to do this already. I'm happy to write a function to convert a sequence of words to an expression, even if it's the 'all combinations' one.

Thank you,
