The search in the help does not work.
I tested with a simple sentence typed manually and with different words.
Sometimes the system finds one word but very rarely, and above all, the search is not updated if the file is modified. Also, still problems with the apostrophe.
in short, it does not work!
Needless to say how important this functionality is when distributing complex software.
it looks like this mod hasn’t evolved for a long time and never fixed, maybe someday you’ll want to take care of that.
In the meantime I have to go through an external module because the search function is very very important! If anyone has an idea, I’m a taker 
Thank you all
Look for an apostrophe in your text and eliminate those found. For instance … the word can’t becomes cannot.
Thanks, I will try !
