The way our Command+F works right now isn’t perfect. On a long section, it unfortunately only searches in the part that’s near the window you are currently looking at.
Upon testing here, it looks like Command+F has the same issue on Chrome as it does on Safari. Are you able to narrow down the issue to just Safari on a specific doc but get the same thing to work on Chrome? Most likely, this is something we would need to look at holistically but would love to know if it’s a Safari-only issue.
Until then, you could use the in-doc search but that’s not the same thing of course. If you are looking to search for something within a table, you might be able to do some of those things using Filtering or Interactive Controls too.
Sorry about the inconvenience!
