Example Solr Queries

Overview

This page has examples of various kinds of queries possible on the GO Solr document store (GOlr), Preliminary schema information can be found in the repo.

Preliminary information about the schema can be found on SF.net.

Usage

The current testing ground for GOlr is:

http://golr.berkeleybop.org/

This is a naked Solr server; you can access it with any http client, including a web browser. In addition, there is an experimental version of Gannet that can talk to Solr (select a Solr mirror from the list):

http://amigo2.berkeleybop.org/gannet

This method is currently a little slower, but may make learning a little bit easier.
