问题 I am trying to implement multiples indices approach using elasticsearch-dsl. There are basically two steps: 1. Create aliases: PUT /tweets_1/_alias/tweets_search PUT /tweets_1/_alias/tweets_index 2. Change alias when necessary: POST /_aliases { "actions": [ { "add": { "index": "tweets_2", "alias": "tweets_search" }}, { "remove": { "index": "tweets_1", "alias": "tweets_index" }}, { "add": { "index": "tweets_2", "alias": "tweets_index" }} ] } I could only implement the step 1 using

问题 I have a small database in Elasticsearch and for testing purposes would like to pull all records back. I am attempting to use a URL of the form... http://localhost:9200/foo/_search?pretty=true&q={'matchAll':{''}} Can someone give me the URL you would use to accomplish this, please? 回答1: I think lucene syntax is supported so: http://localhost:9200/foo/_search?pretty=true&q=*:* size defaults to 10, so you may also need &size=BIGNUMBER to get more than 10 items. (where BIGNUMBER equals a number

问题 Looking to index a CSV file to ElasticSearch, without using Logstash. I am using the elasticsearch-dsl high level library. Given a CSV with header for example: name,address,url adam,hills 32,http://rockit.com jane,valleys 23,http://popit.com What will be the best way to index all the data by the fields? Eventually I'm looking to get each row to look like this { "name": "adam", "address": "hills 32", "url": "http://rockit.com" } 回答1: This kind of task is easier with the lower-level

问题 My mapping is: "properties": { "user": { "type": "nested", "properties": { "id": { "type": "integer" }, "is_active": { "type": "boolean", "null_value": false }, "username": { "type": "string" } } }, I want to get all documents that do not have a user field. I tried: GET /index/type/_search { "query": { "bool": { "must_not": [ { "exists": { "field": "user" } } ] } } } Which returns all documents. Based on ElasticSearch 2.x exists filter for nested field doesn't work, I also tried: GET /index
