Hi all,

I have a problem with sorting ResultSet via SortedResultSet. Here is my code:

            
            ResultSet resultSet = searchService.query(storeRef, SearchService.LANGUAGE_LUCENE, query);

            SearchParameters parameters = new SearchParameters();
            String field = "{http://www.alfresco.org/model/content/1.0}created";
            parameters.addSort(field, false);

            List<NodeRef> nodes = new SortedResultSet(resultSet, nodeService, parameters, namespaceService).getNodeRefs().subList(0,10);
‍‍‍‍‍‍‍‍‍

I want to sort the resultset using {http://www.alfresco.org/model/content/1.0}created field. It doesn't work and I do not know why.

Can anyone help me with this issue?

Thanks in Advance,
Kamil Warcaba

Ha! …. Lucene has roughed me up a couple days and I hope nobody had to go thru the battles I had to go thru.

            
SearchParameters parameters = new SearchParameters();
String field = "{http://www.alfresco.org/model/content/1.0}created";
parameters.addSort(field, false);
‍‍‍‍‍

Try the following:

SearchParameters parameters = new SearchParameters();
String field = "{http://www.alfresco.org/model/content/1.0}created";
parameters.addSort(org.alfresco.repo.search.impl.lucene.QueryParser.escape(field), false);
‍‍‍‍‍

This should work, though, if you want to make life simpler, use the prefix property naming convention:

String field = org.alfresco.repo.search.impl.lucene.QueryParser.escape("@cm:created");
