Thanks @panyam & @franklin52
panyams code returns a slightly different result than franklin52's code on my files. panyams is for me the more correct + suitable. I am a novice on awk, though I figured out that always the preceeding line with getline or {c=2} is returned. There are sometimes more preceeding lines. How would the code be if there are multiple lines? The next number is always one larger than the one where the search string is in.
inputfile.txt
999 some text searchstring some text
some text, some text
some text, some text
some text, some text
1000 some text, some text
some text
1001 some text searchstring some text
some text
some text, some text
1002 ....
