I have a problem. elasticsearch queries data in batches by scroll. no matter how big the batch number is, only the data of the first batch can be queried. no search context found for id...

If you're using the scroll query, it could very well be timing out. You can specify a timeout of up to 1d in the request if that helps.
It's also worth noting that we recommend using search after over scroll in newer versions of Elasticsearch.
