ESGF Search User Guide

General Syntax

Each ESGF Index Node exposes a RESTful URL that can be used to query the metadata holdings of that Node, and of the whole ESGF federation. The general syntax of the search URL is:

 http://base_search_URL/search?[keyword parameters as (name, value) pairs][facet parameters as (name,value) pairs]

A request to the base search URL with no parameters specified will return the search results corresponding to the default values for all query parameters. For example, the following URL will execute a default search versus the JPL Index Node:

 http://esg-datanode.jpl.nasa.gov/esg-search/search

The value of all parameters must be URL-encoded, so that the complete search URL is well formed.
