To be sure that the new sections of your docs are indexed and, therefore, displayed in your search, you'll need to be sure that your crawler configuration is updated. You can do that in the Crawler Admin Console of your Algolia dashboard.
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.
