 v56 ----- = Search of ESGF Climate Data = A search in ESGF returns the records that matching the search constraints after querying to  an index node. The ESGF search service is always served by a index node and this node is able to do local and distributed searches. In this tool, the distributed capabilities of the ESGF are used so any selected index node will be used to query all nodes in the ESGF system. The search panel of ESGF climate data is in the "Search" sub-tab (be patient, the panel takes to load). The search constraints are defined by parameter configuration in the panel or by introduction of a free-text search query. The result are the number of records finding in the federation that satisfy the constraints of search (in panel in bottom right area). Record is the physical replica of a climate dataset that are stored on a data node. A search in ESGF returns the records that match the search constraints after querying to  an index node.
