Is there a script for applying a certain style to several thousands of words arranged in a list?

Question

Hello, I have tried using FindChangeByList, but I'd pretty much do all the work of pasting every word on the brackets, so i could as well apply the styles by hand.
So my project involves applying the same style to around 11 thousand words that appear in a book. Those words are mostly names and brands, and they appear throughout the whole text, so applying that style manually would be quite time-consuming.
I have those words set aside in a list.txt
Does anyone know if I could use that in any script and apply the style automatically?
Like I said, pasting every single word into FindChangeByList is out of the question, just like applying the style word by word, it would take forever...
...thanks!

Okay, for anyone that might be interested in this as I was, I found a solution.
If you want to have a particular text expression on your .txt list to be used as a search parameter by your script, here are a few tips:
Let's say you want to add the following 2 expressions on your list, without the quotation marks:
a) "test, test."
b)"[test] {test}"
1 - Like Jongware said, you MUST abide by GREP syntax.
2 - If you want to put an expression on your .txt list that DOES NOT uses characters that represent GREP syntax (example a) with regular text, commas and simple punctuation), you may simply add them to your list between parentheses:
     a) (test, test.)
3 - If you want the script to search for an expression that DOES CONTAIN characters that are also used by GREP syntax (example b) you can try stuff like:
     b) (\p{Ps}test\p{Pe})
     note the parentheses, because it's a specific text expression
     then note the \p{Ps} and \p{Pe} that mark opening or (s)tarting and closing or (e)nding punctuation such as brackets, braces, parentheses...
Here is a file with the GREP expressions that helped me solve my problems:

Although this is a very specific matter and probably easily solvable by all the professional scripters here, I thought I'd share it since it took 3 whole days of studying for me to conclude everything.
Thanks again, specially to Jongware
