It is designed to provide a scalable, reliable, and feature-rich search platform that can handle large volumes of data. With Apache Solr, you can easily index and search different types of content, including text, images, and even videos. It also offers a variety of features such as spell checking, faceting, and geospatial search, among many others.
If you’re interested in using Apache Solr for your project, the first step is to download and install it. You can download the latest version of Apache Solr from the official website. Once you have downloaded the package, extract it to your desired location.
Step 1: Starting Apache Solr Server
The first step to getting started with Apache Solr is to start the Solr server. You can start the Solr server by running the following command:

Step 2: Creating a Solr Core
Once you have started the Solr server, the next step is to create a Solr core. A Solr core is a collection of documents that are indexed and can be searched using Solr. You can create a Solr core by running the following command:
Command |
Description |
|---|---|
./solr create_core -c my_core |
Create a new Solr core named my_core |

Step 3: Indexing Documents
Now that you have created a Solr core, the next step is to index documents. You can index documents by running the following command:
Command |
Description |
|---|---|
./post -c my_core example/exampledocs/*.xml |
Index all documents in the exampledocs directory |
This command will index all the documents in the exampledocs directory into the my_core Solr core.
Step 4: Searching Documents
With the documents indexed, you can now search them using Solr. You can search for documents by running the following command:
Command |
Description |
|---|---|
curl http://localhost:8983/solr/my_core/select?q=*.*&wt=json&indent=true |
Search for all documents in the my_core Solr core and return the results in JSON format |
This command will return all the documents in the my_core Solr core in JSON format.
