Full Text Index Update
From Gcube Wiki
The FullTextIndexUpdater Service is responsible for feeding an Index. One FullTextIndexUpdater Service resource can only update a single Index, but one Index can be updated by multiple FullTextIndexUpdater Service resources. Feeding is accomplished by instantiating a FullTextIndexUpdater Service resources with the EPR of the FullTextIndexManagement resource connected to the Index to update, and connecting the updater resource to a ResultSet containing the content to be fed to the Index.
