I'm not very familiar with regex at all and was wondering if you could tell me how your regex would handle two matched search strings that exist within a few words of each other in the text. For example "A larger server would be sufficient I think". Also in the link you provided (reproduced below) the first matched word is surrounded by 4 words and the second by 5 words, is there a reason for this? "An example of a larger post can be found ... we were to add a sufficient amount of text than we ..."
