What exactly is "NEAR" for boolean text searches?

Question

What exactly does "NEAR" mean then doing a boolean text search:

NEAR on the same line means what (characters, words, etc)

NEAR across the same file means what (number of lines separating them, number of characters, words, etc.)

I need to search a collection of files for all instances where two regular expressions match within XX lines (4 in my case) and I want to understand how to do this or how to adjust the parameters for NEAR.

Thanks!

NEAR only matches terms if they are found within a certain number of characters from each other, the default is 100 characters. You can change the number of characters in the Configuration Settings or actually specify it in the search term, e.g.

TermOne NEAR:50 TermTwo
