Hey, I use (and wrote) that package for around 30 different tables in a production system, some of which use the advanced search and export functionality - the documentation I wrote is a little out of date - so if you decide to use it shoot me a message as there are a couple of options you may need to apply.
@raragao - I’m working on a new version of this package that will be slightly more performant. It’s probably best if you wait for that. I expect to have it ready in the next week.
@raragao I published the new version today - the only thing you need to know really is that if you use a publication that returns an array of cursors, or utilise the compositePublicationNames property - you must also specify a “good” sort (one where preferably there aren’t multiple valid orderings of documents).
