Search Engine

As a (geo)data portal, geoNetwork's main feature

is search through metadata

All data is stored on the database,

but it is not used for searching

Search is based on Lucene 4.9.0

Configure the fields exposed on index-fields.xsl

Available through the q API service

Web Map Viewer

Part of the basic User Interface

Read-only (view-only)

Geo-related services can be added (like geocoding)

Import and Export metadata
