Size of query ignored?

[nikolang]

I am trying to export 500 of several millions artivles in my ES database. To do so I added the "size":500 - Parameter in the JSON (URL encoded the source-Parameter). This works well for the normal _search but for the _data?format=csv it seems the size is ignored and instead the plugin writes all my million articles into one file.

Can anyone confirm this or give a hint what I am doing wrong?

The default behavior for specifying size is scroll-scan search.
If you want to set a document size, could you try to add search_type request parameter(ex. _data?format=csv&search_type=query_then_fetch).

The plugin still ignores the size. This is my whole curl query:

$ curl -XGET 'http://localhost:9200/_all/_data?format=csv&search_type=query_then_fetch&source=%7B%22query%22%3A%7B%22filtered%22%3A%7B%22query%22%3A%7B%22bool%22%3A%7B%22should%22%3A%5B%7B%22query_string%22%3A%7B%22query%22%3A%22Angela%20Merkel%22%7D%7D%5D%7D%7D%2C%22filter%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22match_all%22%3A%7B%7D%7D%5D%7D%7D%7D%7D%2C%22size%22%3A10%2C%22sort%22%3A%5B%7B%22_score%22%3A%7B%22order%22%3A%22desc%22%2C%22ignore_unmapped%22%3Atrue%7D%7D%5D%7D&fl=title'

My server just worked several hours and gave me back thousands of lines even if the size is set to 10 as you can see.

Oh, please use "from", instead of search_type.
.../_data?format=json&size=10000&from=0&...

Still too many articles. My query:

$ curl -XGET 'http://localhost:9200/_all/_data?format=csv&search_type=query_then_fetch&size=10&from=0&source=%7B%22query%22%3A%7B%22filtered%22%3A%7B%22query%22%3A%7B%22bool%22%3A%7B%22should%22%3A%5B%7B%22query_string%22%3A%7B%22query%22%3A%22Angelo%20Merkel%22%7D%7D%5D%7D%7D%2C%22filter%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22match_all%22%3A%7B%7D%7D%5D%7D%7D%7D%7D%2C%22size%22%3A10%2C%22sort%22%3A%5B%7B%22_score%22%3A%7B%22order%22%3A%22desc%22%2C%22ignore_unmapped%22%3Atrue%7D%7D%5D%7D&fl=title'

Tried it with and without "search_type=query_then_fetch". Both with more than 10 articles

I also have this issue. Any help with limit?
