How to Use

Solr includes a few examples to help you get started. To run a specific example, enter:

  bin/solr start -e <EXAMPLE> where <EXAMPLE> is one of:
    cloud:         SolrCloud example
    techproducts:  Comprehensive example illustrating many of Solr's core capabilities
    schemaless:    Schema-less example (schema is inferred from data during indexing)
    films:         Example of starting with _default configset and adding explicit fields dynamically    

For instance, if you want to run the techproducts example, enter:

  bin/solr start -e techproducts

Developer Documentation

Learn more about developing Solr by reading through the developer docs in ./dev-docs source tree or building Solr from source in ./dev-docs/solr-source-code.adoc

Quickstart

Solr uses Gradle for its build system. Here are some useful hints to build and run Solr locally:

• To build a Solr dev distribution:

./gradlew dev

• To run the Solr dev distribution locally:

cd ./solr/packaging/build/dev
bin/solr start

• Open a web browser and go to http://localhost:8983/solr/ to access the Solr Admin interface. You can also use the bin/solr script to create and manage Solr collections. For example use the bin/solr post tool to index some sample data.
