## Notes

Apache Solr is an open source search platform written in Java and built on Apache Lucene, according to the project's homepage. It runs as a server process that listens on a port once started from its control script, and it is installed from a binary download or a Docker image.

The Apache Software Foundation maintains the project. Its Reference Guide documents the installation and the server.

## Worth knowing

The server needs a Java runtime at or above the minimum that the system requirements page names, so the host must provide Java. As a running process it cannot be hosted as static files.
