I have gotten this issue before and will work on fixing it.

You should not add your own search textfield to the toolbar; rather, you should use the app chooser that already exists. You can add items to it using this code in your AddAppBar function:

        ch := tb.AppChooser()
        ch.AddItemsFunc(func() {
            ch.Items = append(ch.Items, gi.ChooserItem{
                Value: "my search result",
                // etc
            })
        })

Also note that we will work on improving searching support, especially for tables and trees, in #28, #770, and #675.
