No it doesn't.

I think what trying to exclude the .br TLD. Have you tried the "site:" syntax which can include or exclude domains. Loke this:

teste de lingua portuguesa -site:.br

I often do it this way because it used worked in the past, and it works in other search engines.

Well this is a more complex case which includes combining negation with quotation and punctuation marks. I'll bet those factors explain why it didn't work.

Searching for 'Edgar Allen Poe -"The Raven"' does work as intended.

The search I printed was trying to omit some addresses (and I now realize quotes are not necessary and do not help for this specific case), but it did find a result with the term I was trying to avoid as a string.

I'm not an expert, but isn't this as simple as "omitting results that have whatever is found inside the quotes"?

I don't understand why your comment is being downvoted. Downvotes shouldn't be used as a form of simple disagreement. I made a simple question, you gave it a simple answer.

I think that actually raises an interesting question:

Should downvotes be used when a comment states a fact, but the voter knows or believes that fact to be false?

In all fairness, it does work without the quotes.
