While working on some of my addons like data visualisation addon (Update 3.0) or attribute viewer I frequently failed to navigate the node tree quickly with the native Blender's F2 search.
So I implemented the https://extensions.blender.org/add-ons/improved-node-search/#new Improved Node Search addon, that extends Blender with visual indication of found nodes + many more creative approaches to searching - like searching only node groups, nested searching, finding attributes, etc.
Check it out, it's free on the extensions platform, but also purchasable for support ❤️
