Gatherer supports Regex. This search produces 27 results, including all of your example, but also some false positives.

Here is a screenshot of the search terms.

The " get " excludes "gets" and "target" results.

The "m/[.]*/-[1-9]+/" term is the regex, with the leading "m/" and trailing "/" being the signal to treat the enclosed term as regex.

Exclude "until end of turn" to only get permanent P/T modifiers.
