It's not possible to manually trigger reindexing for DocSearch.
DocSearch crawls your site and reindexes once a day.
The DocSearch scraper follows the recommended atomic-reindexing strategy. It creates a brand new temporary index to populate the data scraped from your website. When successful, the crawl overwrites the old index defined in your configuration with the key index_name and deletes the temporary index.
The free DocSearch plan, doesn't include technical web support from the Support team. For further assistance, you can post your question on the Algolia Community Forum or Discord. For front-end issues, you can raise the issue directly on GitHub. In addition, you can review our DocSearch Documentation and FAQ.
