Regex search how to find word "gas" and exclude all words "gasification"

[andypassion]

Hello! Regex search question, i need to find exact word using “search in all files”.
Word that i need to find is “gas” and i want to exclude all results with “gasification”.
What query i need to use?

[andypassion]

I have already tried query : gas -ification
No results

@andypassion Try this

/gas\b/

because it’s not regex.
And you tried to find all notes with gas* but without “ification” word.

Your query should be:
gas -gasification

Or you can try:
“gas”
