name: getText from line 20 to line 100, for example
about: Sometimes, I have a large of content, it slows down the server when I retreive them all, but I only needs the last, say, 100 lines, if it's possible to only get the last 100 lines, it would be very helpful.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Provide an api, like getTextPart (startLine, endLine)

Describe alternatives you've considered

Additional context
I'm retreiving the content in real time, to display it on a different client, so I would like to have the texts in real time, like a less than 2s latency, now when the cotent goes over 1000 lines, the latency goes over 6, 7s - because the content retreiving
takes much longer time due to large nubmer of texts.
Google docs has a feature that you can actually define a start index and end index when you retreive the text, so I would expect Etherpad has a simliar, but it seems that it doens't have one currently.
