hi, this code returns only 10 docs

ISearchResponse result = elasticClient.Search
(
x => x.MatchAll()
);

this one throw exception 500

ISearchResponse result = elasticClient.Search
(
x => x.MatchAll().From(0).Size(int.MaxValue)
);

Thanks.

Hey,

can you show us the exception in the elasticsearch logs or error message returned by elasticsearch? A 500 error usually indicates that elasticsearch threw an exception.

Hey,

so this means that a regular /_search operation against Elasticsearch should also fail? You can try using curl or a browser. If so, you should check your elasticsearch log files, whats up.

This is not a nest issue.
