Find issues by state and keyword. This method returns up to 100 results per page.

When searching for issues, you can get text match metadata for the issue title, issue body, and issue comment body fields when you pass the text-match media type. For more details about how to receive highlighted
search results, see Text match metadata.

For example, if you want to find the oldest unresolved Python bugs on Windows. Your query might look something like this.

q=windows+label:bug+language:python+state:open&sort=created&order=asc

This query searches for the keyword windows, within any open issue that is labeled as bug. The search runs across repositories whose primary language is Python. The results are sorted by creation date in ascending order, which means the oldest issues appear first in the search results.

Note: For user-to-server GitHub App requests, you can't retrieve a combination of issues and pull requests in a single query. Requests that don't include the is:issue or is:pull-request qualifier will receive an HTTP 422 Unprocessable Entity response. To get results for both issues and pull requests, you must send separate queries for issues and pull requests. For more information about the is qualifier, see "Searching only issues or pull requests."
