[MarkLogic Dev General] Filtering values from cts:element-values

[Geert Josten]

Hi DJ,

Many small fragments will work just fine in MarkLogic Server. If you specify a fragment root, you won't notice a difference yourself, apart from changed searching behaviour (and perhaps performance impact). I suggest simply trying it, and see how well it performs.

The thing is that the indexes are always fragment-based, though you can specify searchable paths with functions like cts:search.

Kind regards,
Geert
