How do I combine multiple queries in ElasticSearch

问题

For reference here is the code. I am trying to make a hubot plugin that logs to elasticsearch and then uses hubot commands to search those logs.

https://gist.github.com/4050748

I am trying to retrieve records that match two queries.

{ 
  query: { 
        match: {
          user: "SomeUsername" 
        }, 
        range: {
          date: {
            from: (Date.now() - 3600) 
          }
        }
  },
  size: 50 
}

I was expecting:

• Up to 50 records
• records that had the given user
• records in the last hour

I got:

• up to 10 records
• records that had the given user
• from any time

How do I get all the records with some username in the last hour? Do I need to use match_all with filters? Is what I am attempting unsupported?

In SQL it would be something like:

Select (*) from messages where user_name = ? and time > ?

回答1:

You need to use the bool query to combine different queries together. You can then choose whether each single query must match, should match (optional), or must not match.

For anyone who stumbles on this question and wonders what it looks like to combine a match and range query in ElasticSearch, this example would look like

curl 'localhost:9200/<index>/_search?pretty=true' -d '{
  "query" : {
    "bool": {
      "must": [
        {
          "match": {
            "user": "SomeUsername"
          }
        },
        {
          "range" : {
            "date": {
              "gt": "now-1h"
            }
          }
        }
      ]
    }
  }
}'
