Hi Sir/Madam,
I have a question regarding the query builder API (http://docs.adobe.com/docs/en/cq/current/dam/customizing_and_extendingcq5dam/query_builder.html).
If I have a tree structure as below:
--> Landing
--> Category 1
--> Sub Category 1
- Item 1
- Item 2
--> Sub Category 2
- Item 3
--> Category 2
--> Sub Category 1
- Item 4
- Item 5
What I need to achieve is by using query builder API:
1. Grab 3 items from a given subcategory
2. If there is less than 3 items in the given subcategory, grab from other subcategory under the same category until I get 3 items.
3. All the items in the list need to be sorted by a date attribute in the Item page properties.
What I can think of is to call the query builder twice:
Step 1. Select 3 items from the given subcategory sorted by date attribute. (No Issue)
Step 2. Check if there are 3 items, if not, get the leftover amount from the parent of the subcategory (which is category), but the problem here is I cannot find a way to exclude the query builder API to retrieve item from the subcategory given in Step 1, so there is a possibility my items in the list will repeat.
Step 3. If step 2 working, re-sort the whole list by date attribute.
So my question is if there a way to exclude the subcategory path in the 2nd search? Or is there a better way to achieve this?
My sample code:
Map<String, String> queryMap = new HashMap<String, String>(); queryMap.put("type", "cq:Page"); queryMap.put("path", subCategory.getPath()); queryMap.put("1_property", "jcr:content/jcr:title"); queryMap.put("1_property.operation", "unequals"); queryMap.put("1_property.value", currentPage.getTitle()); queryMap.put("orderby", "@jcr:content/itemDate"); queryMap.put("orderby.sort", "desc"); QueryBuilder queryBuilder = slingRequest.getResourceResolver().adaptTo(QueryBuilder.class); Session session = slingRequest.getResourceResolver().adaptTo(Session.class); Query query = queryBuilder.createQuery(PredicateGroup.create(queryMap), session); query.setHitsPerPage(pageSize); SearchResult searchResults = query.getResult(); for (Hit hit : searchResults.getHits()) { Page childPage = pageManager.getPage(hit.getPath()); if (childPage.isValid()) { pageList.add(childPage); } }
Thanks,
Alvin
