Search for double lines in file

hi, I’m trying to search for the number of instances two lines are together in a set of logfiles from various days.

eg. looking for
in c:\temp\ERRORLOGS_*.log

was trying the following with escape characters:
number of lines whose (it as string contains “1201006141239894201%0d%0a 10308”) of find files “ERRORLOGS_*.log” of folder “c:\temp”

but failing, assuming because it’s looking for all that on one line. Any assistance appreciated
thanks, Steve

Right, the lines are split before being processed individually.

You my need something like

number of lines whose (it contains "120100614123989420110308" and next line of it contains 120100614123989420110308") of files ("pathname")
