 ## Benefit of indexing repositories
 
-{% data reusables.copilot.semantic-index-info %}
+{% data variables.product.prodname_copilot_chat_short %}'s ability to answer natural language questions in a repository context is optimized when the semantic code search index for the repository is up to date.
 
-When you start a conversation with {% data variables.product.prodname_copilot_chat_short %} that has a repository context, the repository is automatically indexed to improve answers to your questions about the code in {% data variables.product.github %} and {% data variables.product.prodname_vscode %}.
+When you start a conversation with {% data variables.product.prodname_copilot_chat_short %} that has a repository context, the repository is automatically indexed to improve context-enriched answers to your questions about the code's structure and logic in {% data variables.product.github %} and {% data variables.product.prodname_vscode %}. For example, you can ask **“How does this repo manage HTTP requests and responses?”** and {% data variables.product.prodname_copilot_chat_short %} will reference relevant sections of your code to deliver an informed answer.
 
 **{% data variables.product.prodname_copilot_chat_short %} will not use your indexed repository for model training.**

 ## About index creation and use
 
 Indexing runs in the background and initial indexing can take up to 30 minutes for a large repository. Once a repository has been indexed for the first time, re-indexing is much quicker and the index will typically be automatically updated to include the latest changes within 5 minutes of you starting a new conversation.
 
 Once an index has been created for a repository, {% data variables.product.prodname_copilot_chat_short %} uses it to answer questions asked by any {% data variables.product.prodname_copilot_short %} user in {% data variables.product.github %} and {% data variables.product.prodname_vscode %}.
 
+> [!TIP] There is no limit to how many repositories you can index.

 ## Excluding content from {% data variables.product.prodname_copilot_chat_short %} answers
 
 Enterprise or organization owners with a {% data variables.product.prodname_copilot_enterprise_short %} or {% data variables.product.prodname_copilot_business_short %} plan can define content exclusions to control the behavior of {% data variables.product.prodname_copilot %} for the {% data variables.product.prodname_copilot_short %} seats they manage.
