adjust this script to show complete lines

[nicob]

I'm using this script for searching in txt or html files. The problem is that it doesn't always show the complete line.

 

for example I search for 'france'. My test.html contains:

http://www.link1.com/ website about france blablabla

http://www.link2.com/ website about blabla and people in france blablabla

 

the result I get:

http://www.link1.com/ website about france blablabla

link2.com/ website about blabla and people in france blablabla

 

So if the keyword is NOT near the beginning of the line it breaks the sentence. So what do I have to modify to get always the complete line??
