Azure Cognitive Search: Push Data to Index

In Azure Cognitive Search, a search index is your searchable content, available to the search engine for indexing, full-text search, and filtered queries. An index is defined by a schema and saved to the search service, with data import following as a second step. This content exists within your search service, apart from your primary data stores, which is necessary for the millisecond response times expected in modern applications. Except for specific indexing scenarios, the search service will never connect to or query your local data.
