What is Facetable in Azure search?
Faceted navigation is used for self-directed drilldown filtering on query results in a search app, where your application offers form controls for scoping search to groups of documents (for example, categories or brands), and Azure Cognitive Search provides the data structures and filters to back the experience.
Where are indexers used in C#?
C# indexers are usually known as smart arrays. A C# indexer is a class property that allows you to access a member variable of a class or struct using the features of an array. In C#, indexers are created using this keyword. Indexers in C# are applicable on both classes and structs.

What are indexers used for?
Indexers are a syntactic convenience that enable you to create a class, struct, or interface that client applications can access as an array. The compiler will generate an Item property (or an alternatively named property if IndexerNameAttribute is present), and the appropriate accessor methods.
Why indexer is known as a smart array?

Why did my indexing request fail?
An indexing request made to the target index was not acknowledged within a timeout period due to network issues. Could not establish connection to the search index in a timely manner. Configure indexers to run on a schedule to pick up from a failed state. Additionally, try lowering the indexer batch size if this error condition persists.
How are indexers implemented in the compiler?
The compiler will generate an Item property (or an alternatively named property if IndexerNameAttribute is present), and the appropriate accessor methods. Indexers are most frequently implemented in types whose primary purpose is to encapsulate an internal collection or array.
