How big is pl? 

Can you
(a) replace 'N' with '.' in the strings in pl
(b) turn your loop inside out and use gmatch [1] over read
?

Something like:

local function slide_over_read(read, pl)
   for patt, tbl in pairs(pl) do
      for w in read.gmatch(patt) do
         -- do something with the matched substring w and table tbl
      end
   end
end
