 An indexer runs automatically when it's created. You can prevent this by setting "disabled" to true. To control indexer execution, [run an indexer on demand](search-howto-run-reset-indexers.md) or [put it on a schedule](search-howto-schedule-indexers.md).
 
+## Indexing data from multiple Azure Blob containers to a single index
+
+Keep in mind that an indexer can only index data from a single container. If your requirement is to index data from multiple containers and consolidate it into a single AI Search index, this can be achieved by configuring multiple indexers, all directed to the same index. Please be aware of the [maximum number of indexers available per SKU](search-limits-quotas-capacity.md#indexer-limits). 
+
+To illustrate, let's consider an example of two indexers, pulling data from two distinct data sources, named `my-blob-datasource1` and `my-blob-datasource2`. Each data source points to a separate Azure Blob container, but both direct to the same index named `my-search-index`:

 ## Check indexer status
 
 To monitor the indexer status and execution history, send a [Get Indexer Status](/rest/api/searchservice/get-indexer-status) request:
