As far as I know, there is not a way to exceed 1000 posts when using 'search:all'. I have a few questions, if someone with more experience would be able to answer.
If there isn't a way to exceed the 1000 posts, is there a way to stagger the 'search:all' so that I can view past posts, so instead of the most recent 1000. Maybe I see 999-1999?
Is there a way to pull specific tags from those saved searches rather than just searching the 1000? For example, when querying 'search:all 1girl' it only shows '1girl' tags from that initial 1000 resulting in <1000 posts. Is there a way to search '1girl' and get 1000 results from the saved searches?
If not, I think a feature where we could create private pools that are made of up saved searches/tags would be really useful for organizing and filtering, since we could search within those saved searches/tags (even if its limited to the 1000 post limit).
