(Sorry for double posting, my bad).
I just noticed why this was not working in the original document:
In the beggining, the word that I want to search is "08/05/2017"
When it comes to the last table, if there is this date written anywhere inside the table, this line will be executed:
So when it goes to the last table, every line is hidden (beside the ones with the "08/05/2017")

I'm trying to fix that. Maybe we can do something to check always if the text "08/05/2017" is in the second column (aRow, 2) of each table. That is because the important rows to keep in this table is just if the date (the word that I'm searching) inside the second column named as "Inicio Previsto" (that means Expected Start") matchs.

EDIT:
I just got it done adding this line to show the last table again:
But now my code is a little bit redundant. When it goes to the last table, first it hides everything, then it shows everything again and finally starts to hide the rows that will not be used. Can we do this in a better way?
