Introduction
Improving the search on your Drupal site is important for making your site better and faster. When you add Elasticsearch, which is a strong search engine, by using the right module, you get quick indexing and more accurate results.
It also helps your Drupal site handle big or small jobs with lots of metadata or even just simple searches. This module lets people who manage the site take care of many different search needs in an easy way.
With Elasticsearch, your Drupal site can give users what they want faster and with better results. This makes the search on your site smooth and more user-focused.
Understanding the Role of Elasticsearch in Drupal
Elasticsearch is a strong search engine made from Apache Lucene. People like it for its speed and how it can handle lots of data. When you add it to your Drupal site, you can quickly put content into the search index. This helps you connect all kinds of content and makes it easier for people to find what they need.
But using Elasticsearch with your Drupal site is not just about getting things done fast. It also lets you pick from different configuration options, so it fits what you want. It can work for small sites or very big, busy ones. With Elasticsearch, the search in Drupal that you do can get much better. It can meet what your project needs, now and as things change.

How Elasticsearch Improves Drupal Search Performance
Operating with Apache Lucene, Elasticsearch gives your Drupal site’s search engine much more flexible options. With elastic indexing, you get faster queries. This lets people on your site see results in just milliseconds. Unlike other ways, this module helps run hard queries without slowing things down.
The module also lets admins set up each index the way they want. You can change settings for node data, metadata, or other fields. This makes search results on the website more accurate. No matter if your database gets bigger over many months or even in one night, Elasticsearch keeps things running well.
This kind of upgrade is important for any high-traffic Drupal site. Regular queries can often slow down your system. By using elastic technology, everything keeps moving fast. Working together, tools like the Elasticsearch Connector and Apache Lucene make your search engine steady and reliable.
Key Differences Between Drupal Elasticsearch, and Solr
Elasticsearch and Solr are strong search engines, and people often talk about them together because both use Apache Lucene. But their design and how they handle growth set them apart.
One main difference is in what they call their data. Elasticsearch has something called an “Index.” Solr uses a “Collection.” Both give options for sharding and replication, so you can break up and copy your data. But Elasticsearch lets you use more than one document type in an index. Solr does not do this easily; you will have to set it up by hand if you want the same thing.
| Feature | Elasticsearch | Solr |
|---|---|---|
| Data Structure | Index with many types of documents | Collection |
| Real-Time Updates | Fast, thanks to elastic replicas | Updates are slower |
| Scalability in Cloud Setups | Works very well with new cloud solutions | Needs advanced configuration |
Lullabot found in their research that Elasticsearch is just built to grow faster and does better in big companies. This is true, especially if the company needs to search to work right away, and they have a spread-out setup.
Setting Up the Drupal Elasticsearch Connector
Configuring the Elasticsearch connector does not have to be hard, but it is a technical task. First, you need to install Elasticsearch in your app. For this, say what type to use and how much disk space you need in the configuration. Then, you also set how your Drupal site will talk to the service by giving the settings for the endpoint in your app.
When this is set up, the Elasticsearch connector module makes things work well. You use Drupal’s own configuration tools. Admins can create clusters and set up servers for elastic indexing. The Elasticsearch connector is at the heart of the search API.
This setup helps your app work well with your Drupal site by making sure it is fast and works right.
Prerequisites for Integrating Elasticsearch with Drupal
Before you set up Elasticsearch, make sure you have the right checklist. You need to cover a few important things:
- Drupal Modules: The Search API and Elasticsearch Connector modules must be in your Drupal app. Use Composer to set these up. This way, you can make steps quicker and easier.
- Server Configuration: You have to check if the Elasticsearch server is inside your app. Use the services.YAML file to set up space on the disk only for the elastic configuration. Be sure this setup is there, as it helps the server work right.
- Tools and Frameworks: You must have Drush command ready, which helps with indexing. It is also good to check your app so it runs on the right images or frameworks.
After taking care of each of these steps, you can start to use Elasticsearch safely with your overall Drupal configuration. This setup lets your search engine grow with your needs and work fast and right.
Installing and Configuring the Elasticsearch Connector Drupal Module
Installing the Elasticsearch connector module is an important step if you want to use Elasticsearch on your Drupal site. To start, download the module. You can use Composer or Drush. For example, you can type composer require drupal/elasticsearch_connector to do this.
When the module is installed, go to Configuration > Search and Metadata > Elasticsearch Connector on your Drupal site. There, you will see a tab interface. Use the tabs to add a cluster and put in the server endpoints. This configuration will help your app’s Elastic Search work well with Drupal.
If you want to set up advanced options, you can connect fields like node structure and metadata. You will also find it flexible because you can reset the index and test server connections inside the admin settings at any time before the site is live. This module will make your Drupal site and Elasticsearch work well without problems.
Optimizing Search with Drupal Search API Elasticsearch
Making your site search better is easy with Drupal Search API Elasticsearch. First, use this API to connect Drupal metadata and Elastic servers. With these connections, you can set up clusters and index your content quickly.
Next, tune it to improve how queries get answered. The API has processors that help clean, filter, and change queries before you get the results. So, if you have a little content or big metadata for enterprise, this search api makes elastic-based searches work really well in Drupal. Your queries and metadata will always be in good hands.
Creating and Managing Search Indexes in Drupal 7 and Drupal 8
Setting up and handling search indexes on Drupal 7 and Drupal 8 takes a few main steps. First, you need to set up the Search API module. After that, pick which nodes, URLs, and metadata fields you want to include for elastic queries. These are the parts you will send to the Elasticsearch clusters.
For Drupal 7, you need to adjust the way your content links to other data. This will help your Elastic server target what you want. With Drupal 8, you get extra help from its split design. This makes it easy to link with front-end apps and work with what’s in your indexes.
Matching your fields the right way in both Drupal 7 and Drupal 8 gives you the freedom to run different types of queries. Make sure to use tools to check your indexes all the time. This helps make sure your metadata moves over correctly, matches server updates, and avoids errors. Elastic indexes in both Drupal versions make things clear and keep your search simple.
Best Practices for Tuning Elasticsearch Drupal Integrations
Improving an elastic-based search engine on Drupal needs regular work. Here are some easy ways to do it:
- Turn on cron jobs so search queries do not slow down. This will help to keep the whole search engine process smooth and automatic on your server.
- Use screenshots when something is wrong. If you notice a problem between the metadata and your Elastic server, screenshots help to find out what that is.
- Make changes to fields or processors now and then. This keeps the settings up-to-date if the content or the way your search engine works changes.
Clicking on visual signs and doing normal check-ups at server endpoints will help keep your search engine strong over time. Good tuning can make your Drupal search engine fast and easy for people to use.
Conclusion
To sum up, adding Drupal Elasticsearch to your Drupal site can make your search work much better. It helps give users more helpful and exact results. When you know what Elasticsearch does and set up the connector in the right way, you can make your Drupal search even better. This works for both Drupal 7 and 8.
Using Drupal Elasticsearch also makes your site stand out from others that only use old search options like Solr. When you use the power of Elasticsearch with Drupal, you get more from your content and keep people coming back. If you want to make your search better, you can always ask for a free consultation.
Frequently Asked Questions

Ans. Drupal 7 needs extra steps to connect its data to Elasticsearch when you want to set it up. But Drupal 8 uses a split structure, so it works better for setting up this search tool. Both of them use modules such as Elasticsearch Connector to work with Elasticsearch. However, Drupal 8 comes with more advanced configuration options built in for Elastic Search features.
Q. Can I use the Drupal Elasticsearch connector with other search modules?
Ans. Yes, the connector works well with search modules that are used with it, like the Search API module. This means you can use Elasticsearch together with other Drupal apps. It helps you get better search engine results and gives you more options to create the kind of indexing you want.
Q. How does Drupal Elasticsearch compare to Solr for enterprise sites?
Ans. Elasticsearch is good at handling growth in today’s cloud systems. It uses elastic replicas to show real-time search results. Solr gives people tools that they can use in many ways, but it needs more configuration to set up. As Lullabot has seen, Elasticsearch is right for companies that want fast servers that work together.
Q. Are there any limitations to using Elasticsearch Drupal for multilingual sites?
Ans. Elasticsearch can work with queries in many languages. But, sometimes there can be problems with special tools or parts that need to be set up for each language. You have to make changes when putting everything together. This makes sure the metadata and the search are right when you use Elasticsearch for your queries.
Q. What steps should I take if my Drupal Elasticsearch search results are inaccurate?
Ans. Check and change the configuration settings. Make sure the processors work well. Run cron jobs to keep the search indexes up to date. Look at the server and see if it is connected the right way. Check the query mapping to be sure the metadata matches what the search engine needs for good results.
