问题 This question is similar to my other question enter link description here which Val answered. I have an index containing 3 documents. { "firstname": "Anne", "lastname": "Borg", } { "firstname": "Leanne", "lastname": "Ray" }, { "firstname": "Anne", "middlename": "M", "lastname": "Stone" } When I search for "Ann", I would like elastic to return all 3 of these documents (because they all match the term "Ann" to a degree). BUT, I would like Leanne Ray to have a lower score (relevance ranking)

问题 What is the difference between Only match and bool must match query in ES?

How to properly write boolean or logic in elasticsearch?

阅读更多关于 How to properly write boolean or logic in elasticsearch?

问题 I want to grab all documents with loId=6 AND (actionType = "SAVE_DATA" OR actionType = "OPEN_SCREEN") . Am I writing this logic incorrectly? Why does my query return 0 results? Note : I'd accept a query or a filter to resolve this issue. These are some sample documents: { "_index": "logs", "_type": "record", "_id": "eIIt3vtrSxmdOVGClQmN3w", "_score": 1, "_source": { "timestamp": 1373569919000, "uid": 6, "paId": 56298, "loId": 6, "prId": 2, "vId": 6577, "actionType": "SAVE_DATA" } }, { "_index

How can i get count of number of rows that have boolean value true(or 1) in Room persistent database without using SELECT query?

阅读更多关于 How can i get count of number of rows that have boolean value true(or 1) in Room persistent database without using SELECT query?

问题 I am working with Room persistent database in my project. I have a table in which there is a column for Boolean values as in 0 or 1, now i want the count of all Boolean values whose value is true (or 1). I know that i can achieve this using select query by getting the count of all selected rows using where clause! But i don't want to use Select query with where clause for this because it will load all the rows and then i will get the count, but i want the count without loading any rows!

Elastic query DSL: Wildcards in terms filter?

阅读更多关于 Elastic query DSL: Wildcards in terms filter?

问题 I am trying to filter the documents using terms filter. I am not sure how to introduce wildcards in filter. I tried something like this: "filter":{ "bool":{ "must":{ "terms":{ "wildcard" : { "aircraft":[ "a380*" ] } } } } } But I get SearchParseException with this. Is there no way to use wildcard within filter framework? 回答1: The terms filter doesn't support wildcards, queries do, though.
