Difference between -filter:retweet and -filter:nativeretweets in Twitter Search API 1.1

Question

I'm trying to run some queries against the Twitter API to collect some tweets. I want to filter out retweets and after some research discovered there seems to be two different tags you can append to the search query to filter them -filter:retweet and -filter:nativeretweets.

I've ran sample queries with both options and can seem to tell the difference. List is returned tweets is slightly different but in no real way I can discern. Neither seem to contain retweets. I won't post the output here as it's a fairly length JSON output but I can if need be.

The sample queries are

-filter:retweet

-filter:nativeretweets

Answer 1

I believe per TweetDeck documentation (https://support.twitter.com/articles/20170322) this is the difference:

filter:nativeretweets shows retweets from users who have hit the retweet button. filter:retweets shows old style retweets ("RT") + quoted tweets.

Those are filtering FOR those types of results, but as you've done, the - is necessary to filter them out -filter:nativeretweets or -filter:retweets
