I’m not a developer for SketchUp. I don’t even work for Trimble. I can’t aswer your question. Maybe a search feature could be added some day. I was only offering a suggestion that works now so that the OP isn’t dead in the water until such time as the feature is implemented.
When it comes down to it, a search feature for components is something I personally wouldn’t use. I’ve never once wished for it myself. Of course I’m just one user and clearly it is something that others could use so maybe it will appear in some future version.
