Alright so it used to take me ages to find specific things in studio but I figured out how to use all the capabilities of the search tab in the explorer. So I’m going to show you aswell 
Basically think of the search bar as an if statement but with a slight different syntax
Useful features
The search bar has loads of useful features.
For example you can search for any type of object just by typing classname:"classNameHere" or get any part with a mass equal to 5 mass = 5
Symbols
These a pretty simple and are the same for when scripting.
If you use > after a property then it will be anything greater than x. e.g mass > 10 will show anything with a mass higher than 10
If you use < after a property then it will be anything less than x e.g mass < 10 will show anything with a mass less than 10
If you use = after a property then it will be anything equal to x e.g mass = 10 will show anything with a mass the same as 10
The equal symbol can be combined with the greater or less symbols. e.g mass >= 10 will show anything with a mass the same as 10 or a mass above 10
Telling the difference
Now I am no expert on why certain things use a colon and others use the decider symbols but I can tell you which I know use colon and use equal
The ones I know
tag:classname:anchored=mass=cancollide=archivable=locked=visible=transparency=
There are many more but I rule of thumb I noticed was if it’s underlined in red the your probably not using the right thing
Chaining
Same as scripting again really.
You can use and or or to chain it so mass=1 or anchored=true will show many any object with a mass of 1 or is anchored, mass=1 and anchored=true will show many any object with a mass of 1 and is anchored.
The end
So hope I didn’t bore you to sleep and you find this useful. It really did speed up my workflow and I hope it does for you to. Feel free to ask any questions you have and I will try to respond to them. Enjoy
