For example: the line - "all this is here to here, and then there is a lot more to here". The substring to which you need to bring everything up to here, you need to get everything that's it.

The problem is solved using the following regular expression (PCRE):

(.*?)досюда

In the first match (Match 1) will be the required substring.

Attention should be paid to the "lazy" quantifier ( .*? ). If he were ordinary, i.e. greedy ( .* ), the result would be slightly different than expected. Greedy Quantifier for String

 "все вот это досюда, а дальше там еще много всего досюда"

will give a match

 "все вот это досюда, а дальше там еще много всего "

while the "lazy" will give quite the expected result:

 "все вот это "

    the most logical solution is to delete the desired word and all characters after it:

     s/досюда.*//

    in the line will remain only what is required.

       "any text any text any text<stop>other text other text ...".match(/[\s\S]*?(?=<stop>)/)
