Is searching for all occurences of a term really slow now?

Before the update, I could easily search for all occurrences of a term in a document quickly via ctrl F.

Now, I use ctrl F then select Filter to search for a term: shows 0 result. While the term is in fact in a child rem.
I went to that rem. Stare at that term for a few seconds. Went back to the document outside. ctrl F → Filter: search for that term again: dozen of results show up.

This happens frequently.

It seems the search simply takes much longer than before.

In RemNote 1.4, Ctrl + F is Find, Ctrl + Shift + F is Filter… Is it different on your Keyboard Shortcut?

I think Find is faster than Filter, But Find does not search for Hidden rems…

yeah I meant Filter. What I did was Ctrl F then select Filter.

In previous version there was simply Ctrl F to find all occurrences of a term in a document within seconds. Now the simple function has been split into Find (which is relatively useless) and Filter (which is always what I need but it often shows 0 result because it’s too slow) and Replace (which I haven’t really needed to use)
