Hello I have a parent-child index in my app (mapping gist: https://gist.github.com/zwrss/9953291#file-mapping). I have about 250.000 parents and 7.000.000 childrens. I was trying to speed up my top_children query (gist: https://gist.github.com/zwrss/9953291#file-parent-query) a bit, so I tried adding some filters to ensure that the query have to score only about 300 parents (gist: https://gist.github.com/zwrss/9953291#file-filtered-parent-query). The effect was surprising - the original query was executing in ~150 ms and the filtered one in ~270 ms. I thought that adding some filters to ease the scoring process would help. I thought that te top_children is the thing here so I decided to do some testing and tried to query only Children and add some filters to narrow the results. The original query I tried (gist: https://gist.github.com/zwrss/9953291#file-child-query) executed in ~90 ms and the filtered one (gist: https://gist.github.com/zwrss/9953291#file-filtered-child-query) in ~120 ms.
Is that the correct behaviour? Am I missing something? best regards Paweł Młynarczyk -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
