Dr Bainbridge fixed the issue in the solr-haminfo whereby the rawquery sent off in map-scripts::performProximitySearch() didn't return any results. The solution was to change the collectionConfig.xml file to include the searchType raw. As this was a format statement change, no need to rebuild the collection. 2. Added a README including the outstanding tasks to do with the map-editor, and not-yet-working uncommitted java code changes to handle a request for descendants.
