Comment 4 for bug 1174529

Yes, quick-search feature and Ctrl-F do the same. This
1) makes them reundant.
2) makes quick-search mostly unusable for the original purpose - that is, quick selection of a file without having to scroll through long lists. Suppose the user wants to find ".profile" in $HOME.
Expected behaviour: type ".p" and it would be 2-nd or 3-rd file after selected.
What happens instead: the first pressed key nearly freezes nautilus as it tries to dig through the whole $HOME/* tree - then it may eventually show every ".*" file down there or may freeze completely. Until then, it does both intense disk seeking and CPU consumption. The problem: even in best-case scenario, scrolling a long list is faster by many orders of magnitude in any place with big subtree, like $HOME or /usr/share. Meaning quick-search is almost useless for quick searching.
Both points mean it's a bug.
