Search techniques have been formalized by the user .The device to use it is needed.
It is good that images could be found that could not be searched previously.
It is good that searches can be done with objective information.
It is hard to determine the composition in advance when searching.
Want it to support people searches.
Want it to also support searches of image motifs with different color shades.
Can tolerate to some extent search accuracy deviation, and the time it takes to search.
It reaffirmed the expectations of users.
It is helpful for such things as searching for images that are prohibited from use.
