It is not possible with [text search] if i am right.
I think you should outline your use case/problem in more detail. This
should be a good practice when asking for support on the Mailing List.
Example:
1) I have a text file where each line contains a two integers separated
by a space (" ") char - such as (possibly paste a part of the file on
pastebin or similar too).
213214 12313
123223 13213
2) My file is [always/at least/circa/ ...] 2,539,592 lines long
3) My algorithm should find all subsequent lines matching the first line
in the file and return [all line numbers for matches / the total count
of matched lines / ...]
3) I want the algorithm to be [as fast as possible / run in under 1
second / run in under 1ms / ... ]
4) I [want to / do not need to] use Pd Vanilla
5) My patch should run on [All platforms / Windows / OSX / Linux / ...]
6) My patch should run [on potentially any machine / on a Raspberry Pi /
on a 1990s 386 machine / on my digital toaster where I have compiled a
custom version of Pd / ... ]

You can also use [text search], although t's not so easy to find more
than the first instance. If you don't mind taking a extra step, you
could give each line a third term, which is the line number. Then you
can use the "> 3" argument for [text search] to find matches s

*Subject:* [PD] Fastest way to find lines in text file
Hello,
I need to find every lines of a textfile containing a word.
The textfile has 2.539.592 lines.
Now, i am using [msgfile] from zexy because i can find a line, skip a
line and find again ... until the end of the textfile.
But, i am wondering if there is an other object (in an other library)
faster, specialized in this work ?
Thanx.
