Can I query Azure Search while the index is being updated?

Question

I need to run an Azure Search indexer to rebuild an index on > 10 million documents. If this is a long running task will the Azure Search be available to query?

Answer 1

Yes, you can query an index while documents are being indexed. However, there are several things to be aware of which I mention in my Azure Search tutorial,

1. The document(s) will not be part of a result set until they have been indexed.
2. Indexing this many documents could potentially slow the performance of your queries.
