LPS-51880 Adds new methods to search for more than one ddmStructureKey
LPS-51880 Creates a new method to returns the articles depending on if we index all versions or not. We have two cases:
 - If we reindex all versions, we should return all articles filter by ddmStructureKeys
 - If we don't reindex all versions, we should return the latest version of each article filter by ddmStructureKeys
LPS-51880 Uses the new method
