Watch list: "Rescan Topic" timeframe

Postby astrax » Sun May 12, 2019 7:59 am

To filter out NZB files from a group of groups, I set up a watch list.
To get older files from those groups I regularly add older posts. But each time, I use "rescan topic" to scan for new files for that list, NB goes through all the data it already went through.
Especially with a large number of header this can take sometimes hours, or even days.
Is there a way (or could there be in the future?), only to scan from a certain point on, so NB doesn't have to go through all those headers again? Like saying, "only scan headers from xx month ago to oldest availabe".

THX.

The question is why are you even doing a "rescan topic" in the first place? It's intended to pre-load your watch list from existing headers then you never have to do it again because new header downloads automatically feed to the watch list.

It never occured to me, it works this way. Never noticed either. OK, now that you say it...
I thought, the watch list would only scan headers that had already been loaded and the new ones, that would be added with every update. Not the ones that are loaded via "load xxxxx older posts".

So, in what case would one use "rescan topic"?

1 - You make a new watch list and want to feed it from the headers you already have on disk.

2 - You make a change to how your current watch list filters and you want to re-scan and pick up the changes.

3 - You delete everything from an existing watch list maybe because of 2 and you want to re-feed the list.
