feat(Edit Mode) #30799 : Fixing error reported via IQA

[jcastro-dotcms]

Proposed Changes

• Fixing this error found by @freddyDOTCMS when doing the IQA:

Needs work: We don't have a way to list the contentlet from all sites, if you sent the "siteId" it return the Contentlets for this specific site but if you remove it then it return just the Contentlet from SYSTEM_HOST

• Also, adding some Javadoc to the SearchView class to explain what the queryTook and contentTook properties mean.
