# What Is Amazon CloudSearch? {% hint style="info" %} This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/amazon-cloudsearch-developer-guide.git) {% endhint %} ## Automatic Scaling * **Note**\ If your domain has scaled up to accommodate your index size and you delete a large number of documents, the domain scales down the next time the full index is rebuilt. Although the index is automatically rebuilt periodically, to scale down as quickly as possible you can explicitly [run indexing](https://github.com/kevinslin/aws-reference-notes/blob/main/services/amazon_cloud_search/indexing.md) when you are done deleting documents. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://awsnotes.dendron.so/analytics/amazon-cloudsearch/topics/what-is-amazon-cloudsearch.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
