My question is general and concern actual, but mostly future pipes of mine, so no link to a specific pipe.
I was wondering about the rules governing the selection of the item displayed after going though the 'Unique' module black-box. Nothing about it is mentioned in the short documentation. Is it the older match? Is there a way to express our preference?
What about the possibility of saving specific sub-items of the several matching items into the one item displayed? (such as comments...)
found out today. the answer is, firsts in feed are kept, next are dismissed. Hence the correct use of the union module which puts items of the leftmost linked feed first, then second left etc till the rightmost last.
