I tried installing the compare plug-in and after auto-restart the compare plug-in was still not there. So next time I did a manual restart and it worked.

Hi, @vasile-caraus, Now, I realized that the regex, given in my previous post, (?i-s)(Word1).*?(Word2)|(?2).*?(?1) could be simplified ! Indeed, as I explained, we can’t use back-references, which are not defined if the regex engine choose the second alternative ! But, when the boundaries Word1 and Word2 are not, themselves, regexes ( as, for instance \d+, a..z… ) and rather simple strings, we can use the more simple syntax below : (?i-s)Word1.*?Word2|Word2.*?Word1 Secondly, to select any entire line ( with its EOL characters ) containing the two words Word1 and Word2, whatever their order, use the regex, below : (?i-s)^.*(Word1.*Word2|Word2.*Word1).*\R Best Regards, guy038 P.S. : As we’re rather dealing with exact words, we should use, instead of the two above, the regexes, below : (?i-s)(?<=\W)Word1\W.*?\WWord2(?=\W)|(?<=\W)Word2\W.*?\WWord1(?=\W) and (?i-s)^.*\W(Word1\W.*\WWord2|Word2\W.*\WWord1)\W.*\R

@John-Pilge Your technique works most of the time, but there are limits to how much text you can put into the “Find-what” box. As an example on the above text, it ALMOST but not quite will handle it all. For me, it will do the text from the start up until "All parcels will ".
