This is a POST request and you are passing the query with the -d parameter. # added pretty=true to get the json results pretty printed # query for documents / rows with title field containing 'jones'
Anyway, there are several ways to do it using the terminal. Or maybe you don’t trust it, because it so happens that sometimes results differ when you query from ES-head and from terminal. Why do it from terminal when there’s a nice ES web console (elasticsearch-head plugin)? Well suppose you don’t have an ES web console. Actually, its purpose is to remind myself of the ways to query ES from terminal. There are multiple methods for configuring which fields you want to get.This will be a very short post. If you combine both a large size parameter and many fields, together they will significantly slow your search speed.īecause of that, it’s recommended to only get the fields that you truly need. This is due to the same reason we mentioned earlier – Elasticsearch will need to construct and transfer more documents to the client. Similar to retrieving more documents than you need, getting too many fields you don’t use will also slow down your search speed. header 'Content-Type: application/json' Get only the fields you need You can change the size in the search parameter: curl -request GET \ It’s recommended to double check and ensure that you set the value to the amount of documents you need. Other than that, the transfer latency between Elasticsearch and the client will also slow the search speed. A large value in the size parameter will reduce your search speed because a large number of documents need to be constructed by Elasticsearch. Size parameter in Elasticsearch determines how many documents Elasticsearch will return in responses. Don’t put a large number on size parameter A bad query that collects more document results than needed will decrease your search speed. Optimizing your queries is one thing you can do to improve Elasticsearch’s search performance. The Gateway allows for easy detection of slow searches and automated actions to block heavy searches and prevent them from breaking your cluster. If you’re suffering greatly from search latency issues, Opster’s Search Gateway might be the best solution for you.

You’ll receive customized recommendations for how to reduce search latency and improve your search performance. With Opster’s Analyzer, you can easily locate slow searches and understand what led to them adding additional load to your system. If you’re suffering from search latency issues or poor search performance, you should run Opster’s free Search Log Analyzer to optimize your searches. If you want to know more about slow logs, you can check out our article on how to configure slow logs properly.
To configure it on the Elasticsearch level, you can change the properties: .query.warn: 10s header 'Content-Type: application/json' \ To configure it on the index level: curl -request PUT \ You can configure slow logs on the index level or Elasticsearch level. When configured correctly, Elasticsearch will print any slow query you can debug so you can improve those specific queries. Here are a few different ways you can do so: Using slow logsĮlasticsearch provides a very convenient feature called slow logs. How to detect slowness in your Elasticsearchīefore we learn how to increase your Elasticsearch search speed, it’s important to first cover how to detect the slowness in your Elasticsearch. In this article, we will detail how to increase Elasticsearch speed by optimizing query and Elasticsearch settings. Most of the time, it’s the reason people decide to use Elasticsearch in the first place – which is why it’s key to ensure it produces results quickly.īy optimizing and maintaining Elasticsearch search speed, you can improve your product’s user experience and in turn improve your product’s conversion rate. Search speed is the major selling point of Elasticsearch.
