    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

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.
