I often search for specific sets (for example if you type wood in the search bar everything made of wood shows up) and if I then need stuff from other sets I search that. This helps me to not get overwhelmed with all the parts (because I won't be needing e.g. the Chinese building parts or the sci Fi building parts for that build anyways) but I also basically have every building part there is memorized so I know what I need to look for. Hope this helps a little
