Where can i find search window in DT3? (DT2 - CMD+SHIFT+F)

there is top search bar in DT3

but i need more search options

i want separate search window like this

i know top search bar has advanced option too
but i need many search windows + main window

Welcome @SiD

This is not possible as that separate window is not a part of DEVONthink 3.
You should check out the built-in Help > Documentation > Windows > Main Window > Search Pane and the Appendix > Search Prefixes sections.

thanks for answer, separate windows is impossible in DT3

reinstall DT2 problem solved

Do note: DEVONthink 2 will be in maintenance mode, i.e., it will only receive critical fixes (like crashes on startup) going forward. Upgrading to DEVONthink 3 is the advocated option for the long run.

i already bought DT3
didn’t know theres no separate windows
take that feature for granted
I’m ashamed of my folly

No need to feel ashamed about it, but the functionality you’re asking for is still included in DEVONthink 3… and even more than in DEVONthink 2.
