What are the best practices and considerations for using integrated indexes along with a crawler in Acquia Search powered by SearchStax?

Integrated indexes provide more control over the relevancy and customization of search results as they allow you to manage and enhance the content being indexed. A crawler indexes all content, including content that might not be optimized or structured for search relevance. If you combine both approaches, you can address gaps in search results by capturing content that might be overlooked due to configuration oversights.
