URI search query with size -1 doesn't return all the results

Elastic Stack Elasticsearch

Hi,

I am using version 6.4.2 and when I run a URI search like:

GET my_index/_search?q=version:197&size=-1

I expect that all the hits will be returned, but I get only 10 results out of the tens of hits that should return.

Setting size=-2 returns an error (which is expected) and setting size to any number above 10, returns the requested size (if enough hits are available).

Is there a known bug about this or is size=-1 not supported for URI search?

Thanks.

I have never heard about this -1 value.

Anyway, to extract all data if above 10000, use the scroll API.

Thanks David.

Thanks for clarifying this.
