tweets-search is for a question that comes back. Save a query for a brand,
topic, or phrase, then run the same query again later with the same language
and max_results values. That makes the next result set comparable to the
last one.
The request accepts familiar Twitter-search filters. since: and until: are
translated to the current search parameters, and -filter:retweets keeps its
usual meaning. The route returns post text, timestamps, public metrics, and
author fields.
Sometimes the primary X search cannot answer. In that case the response keeps
the same tweets array but sets degraded: true and labels the public-index
fallback. Treat it as a useful current lead, not as a like-for-like primary
search result. The route stays read-only and doesn't change an X account.
