X API Archive Search Data Availability Issue

Based on the information provided, you're experiencing an issue with the X API v2 Full-Archive Search where certain time periods in 2024 (June, late July, early October) are returning zero tweets for your query food -is:retweet -is:reply, despite these date ranges working previously.

Possible Causes

There are several potential explanations for this issue:

1. Future Dates: The dates you mentioned (June 2024, July 2024, October 2024) are in the future. The Full-Archive Search API can only return data from March 21, 2006 to the present date, not future dates.

2. API Index Issues: According to the documentation, data should be available in the index within 30 seconds of generation on the Twitter/X platform. If there's a technical issue with the indexing system, it could cause gaps in data availability.

3. Rate Limiting: The API has rate limits at both minute and second granularity. Partners are limited to a maximum of 20 requests per second, aggregated across all requests. If you've exceeded these limits, it might affect your results.

Troubleshooting Steps

Here are some steps you can take to diagnose and potentially resolve the issue:

1. Verify Date Parameters: Double-check that your fromDate and toDate parameters are correctly formatted and represent past dates, not future dates.

2. Try Different Queries: Test with different search terms to see if the issue is specific to your current query.

3. Check Smaller Time Ranges: Break down your search into smaller time ranges to see if the issue persists across all periods.

4. Contact X Developer Support: Since this appears to be a sudden change in behavior for previously working date ranges, it might be a platform-side issue that requires attention from X's support team.

Remember that the Full-Archive Search endpoint is only available to Projects with Pro or Enterprise access, and the authentication must use OAuth 2.0 App-Only with an App Access Token from a Project with the appropriate access level.
