Different results with same keyword Rest API - Streaming API


If I do a search with the REST API using one keyword , I get a different result from the same search with STREAMING API
With STREAMING API tweets get more. How it’s possible ?
Thank you


The answer’s in the documentation. It says

Before getting involved, it’s important to know that the Search API is focused on relevance and not completeness. This means that some Tweets and users may be missing from search results. If you want to match for completeness you should consider using a Streaming API instead
