How does Azure Search Service know which indexer to search?

Question

I have 5 indexers created for Azure Search Service. How does Azure Search know which indexer to search in? For example: I have indexer for the details of a purchase order, another indexer for supplier details, another indexer for categories. I searched for 999 and Azure Search searched in Detail and Supplier indexer. Why did it not search in category indexer?

When creating the search client, you need to specify which index you want to fire the searches against:

SearchServiceClient serviceClient = new SearchServiceClient(searchServiceName, new SearchCredentials(adminApiKey));
var indexClient = serviceClient.Indexes.GetClient(indexName);
