问题
We are using Azure Search for various scenarios. We often need to update an individual document with changes that users make. We need to have these changes become visible in our indexes as soon as possible so that the stale time is as short as possible within reason.
What is the best strategy to handle this. We know that batch updates is the way to go but we need more immediate reflection of the changes.
Once a document is updated, how long does it take for the index to reflect this change.
Many thanks

If the updates are not very frequent, you can simply update the Azure Search document immediately (that is, using batches of size 1). On the other hand, if the updates are extremely frequent and you notice a high rate of failures with single-document batches, you will need to build some sort of "collector" mechanism to batch up updates. My recommendation would be to do the simple thing first: try single-document batches, and add batching logic if necessary.
Updated or newly indexed documents are reflected in the search results after a short delay, usually ranging from single milliseconds to 1-2 seconds. The delay depends on the service topology and indexing load.
