Is there a way to do a real exact match in Google?
Quotes or plus do not make it exact.
I'm trying to search for the phrase "offset 0", but the results contain "offset: 0", which is not the same and not what I'm looking for.
I've encountered such a problem with many other queries, too.
Try Yandex. It's a Russian search engine providing the opportunity to search with an exact match as well as other options (for example searching a word by entering first X letters and leaving out last Y letters etc.).

In your particular case it doesn't look possible.
As Google Search Help says:
Generally, most punctuation and special characters are ignored...
While that bit is specifically about the search term, it also appears to apply to the index as well. It looks to me that Google doesn't store (or at least doesn't search) content that is punctuation.
Even using the verbatim tool doesn't help.
I even tried "offset 0" -"offset: 0" but the colon is ignored in the index.
Other search engines might do it differently, but I doubt it.
