build with docker

部署 elasticsearch 服务

# pull images
docker pull docker.elastic.co/elasticsearch/elasticsearch:6.6.2
# run elastic server
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.6.2
# search
curl http://127.0.0.1:9200/\?pretty
curl http://127.0.0.1:9200/_search/\?pretty

easticsearch client

https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/index.html
可以使用 curl

curl -X GET "localhost:9200/_count" -H 'Content-Type: application/json' -d'
{
    "query": {
        "match_all": {}
    }
}
'

也可以通过其他 web client 访问，比如使用 javascript

npm install --save elasticsearch
// create a client
var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
  host: 'localhost:9200',
  log: 'trace'
});
// ping
client.ping({
  requestTimeout: 30000,
}, function (error) {
  if (error) {
    console.error('elasticsearch cluster is down!');
  } else {
    console.log('All is well');
  }
});
// search
client.search({
  index: 'twitter',
  type: 'tweets',
  body: {
    query: {
      match: {
        body: 'elasticsearch'
      }
    }
  }
}).then(function (resp) {
    var hits = resp.hits.hits;
}, function (err) {
    console.trace(err.message);
});
