In section Filtering, subsection Fixed string matching, the command $ awk 'index($0,"a+b")' eqns.txt should return all lines of the input file, since a+b appears in each line, right?

thanks a lot for spotting the issue..

I checked my local copy and seems like I had changed first line of input from a+b=c to a-b=c but forgot to change it in the sample shown.. that way, there will some lines matching and some not matching..

I'll change it..
