I have to calculate a difference between "number of results" vs. "number of results for a slightly modified query". The "number of results is known", and I am using the "/\_count" API to get the number of results of "slightly modified query". Problem is, I have to run many such "slightly modified queries", one for each displayed facet =\> 50 "/\_count" queries. The difference in numbers will show user how many results he will get after clicking on a facet. The queries are almost identical -- is there a way to leverage this fact? Some caching hints? Submit all queries to ES at once, instead of calling /\_count fifty times? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
