Find/change should be able to include any text boxes anchored in the search of a text box/story/selection. I use anchored text box objects in tables a lot, and on occasion, it would be helpful to be able to make a change to all the text with a certain paragraph style in a story, but not in the whole document. But with anchored objects, find/change won't see any text in anchored objects if you select the text box with the anchors, and you can't select multiple anchored objects at the same time. This makes it impossible/useless to find/change multiple text items in anchored objects at one time.
