Hi

I have a doubt about two kind of links, that are very similar in functionality: id links with search options and <<target>> links

What would be the best option?

In terms of performance, id links could be better, since the search is narrowed to the contents of a headline, while <<target>> link has to search in several files?

Any other consideration?
Easiness to automate link generation?
Bidirectionality?
Time proof?
Scalability?

Best regards
