public final class Conjunction
extends Association

Conjunction associates Selectors together with the Operator.AND. Here is an example of how to use create a query with 'AND' and 'OR' conditions by using Conjunction and Disjunction. The example will process all content whose name starts with 'news', or whose name starts with 'article' and has a keyword 'news'.

  QueryService queryService = workspace.getQueryService();
  Query query = queryService.createQuery(Content.class);
  Disjunction or = new Disjunction();
  or.add(Selectors.nameLike("news%"));
  Conjunction and = new Conjunction();
  and.add(Selectors.nameLike("article%"));
  and.add(ProfileSelectors.keywordsContain("news"));
  or.add(and);
  query.addSelector(or);
  try
  {
     ResultIterator resultIterator = queryService.execute(query);
     while (resultIterator.hasNext())
     {
        Content childContent = (Content) resultIterator.next();
        if (childContent.hasComponent("myElement"))
        {
           contentWithMyElement = childContent;
           break;
        }
     }
  }
  catch (QueryServiceException e)
  {
     // Handle exception
  }
