The one in the screenshot are property types in AEM but I think the one you are looking for are resourcetype for fields in AEMHere is the granite documenthttps://helpx.adobe.com/experience-manager/6-3/sites/developing/using/reference-materials/granite-ui/api/jcr_root/libs/granite/ui/index.html https...

Can you share the query where you used like clause ?

In order to retrieve value you can use any of these${currentPage.language.toString}${currentPage.language.language}Just in case you need API references-https://helpx.adobe.com/experience-manager/6-3/sites/developing/using/reference-materials/javadoc/com/day/cq/wcm/api/Page.html#getLanguage()

Similar issue was also reported for 6.3 as well.Make sure you do not have any space in path to jar file else it will through an crypto exception in stderr.logReferences from Windows OSPath with spaces - C:\AEM Stuff\aem 6.4 - will not workPath without spaces - C:\sample\aem64 - will work

This is not the exact code which you would need but should help you to proceed.import com.day.cq.search.Predicate;import com.day.cq.search.eval.AbstractPredicateEvaluator;import com.day.cq.search.eval.EvaluationContext;import org.apache.felix.scr.annotations.Component;import org.slf4j.Logger;import ...

By "search engine" are you referring to search query in AEM or some external search engine like google...?

1 .Make you have proper configs in editconfig https://helpx.adobe.com/experience-manager/6-3/sites/developing/using/components-basics.html 2. Someone would have added custom action which might be causing the issueand if its even happening with OOTB components, share component name and steps to repro...

For siteadmin action files in classic ui, you can refer to /libs/cq/ui/widgets/source/widgets/wcm/libs/cq/ui/widgets/source/widgets/wcm/SiteAdmin.Actions.js

Its Classic UI multifield, so I am assuming you would have written custom widget.The format in which you want to store values can always be customized in setValue method.

Two questions:1. What you want expected output to be.2. You are seeing in issue in 6.3 or 6.1 ( I am not clear on last statement "The above code appends an index 0,1 and so on for each node created in AEM 6.3 but doesn't add the index in AEM 6.1.")
