I use sometimes the regex that finds paragraphs
containing given words w1,w2,... in any order ( I define "paragraph"
as separated by lines, \n\n).
I use the pattern like this: (two-word example, w1 and w2, but easily
expandable for N words):
/\c\(.\|.\n\)*\<w1\>\&\(.\|.\n\)*\<w2\>
(and I set :set maxmempattern=20000 )
This works. But search time is unbelievably slow on big files.
My question is; is there a rewrite of this regex that works faster.
To see the testcase how of how slow this works:
1. wget http://www.vmunix.com/~gabor/c/draft.html
# this is ~1.3 MB file.
2. vim draft.html
3. /\c\(.\|.\n\)*\<w1\>\&\(.\|.\n\)*\<w2\>
This search never finishes for me.
How can I rewrite the regex to search faster ?
