Hi Jose, AFAICT, communities2item is used only in these 2 places: https://github.com/DSpace/DSpace/blob/dspace-3.1/dspace-api/src/main/java/org/dspace/search/Harvest.java https://github.com/DSpace/DSpace/blob/dspace-3.1/dspace-api/src/main/java/org/dspace/browse/BrowseEngine.java So it seems the only thing it's used for is determining which items have been added/removed/changed within a community, which is implemented in the following use cases: * OAI server (only up to DSpace 1.8) * user's subscription notification * JSPUI feeds The table is not created staticaly, i.e. not in database_schema.sql. The class that seems to fill this table seems to be the BrowseDAO (e.g. BrowseDAOPostgres). I'm not sure how to forcibly invoke it, but index-update or index-init would be a safe bet.
