OK, I'm going crazy trying to figure out how to do this, and perhaps there is a very simple solution, hope someone can help.
I have 26 pairs of numbers. Not consecutive pairs just pairs so for example -
16,25
3,7
12,21...up to 26 pairs
Now how can can I use EL to filter with the following conditions
1. remove all lines that do not have any of these pairs
2. remove all lines that have 3 of these pairs
3. in effect keep only lines that have 1 or 2 of these pairs in them
How can I do that ? Group filters? or is there a simpler way? Would appreciate any help with this?
