I have a fairly simple question: Is it somehow possibly to see more than 40 pages of posts you made?
That's the search results cap, but you can filter it differently to have those cut off posts show up via a different search.
For example, if you're just looking up all your posts and all the old ones are cutting cut off by the limitation, you can search your posts again but this time sort it to show the oldest first, so it's the newest that are cut off. Combine them and ta da.
