A few keyword corrections for IMDb staff to make

Dear IMDb staff: can you please make the following keyword corrections? 1. films-about-indians (34 titles) The keyword is improperly formatted. With that said, 100% of the titles that currently have this keyword have Native American characters, so the keyword should first be merged before it is blocked. a. The keyword films-about-indians should first be merged into native-american. b. After the merger, the keyword films-about-indians should be blocked from future use. 2. imax-version (23 titles) This keyword is improper because it lists alternate versions of a title. That sort of info should not be in keywords. Much like the blocked keyword "not-on-dvd," this one should be blocked as well. a. All instances of the keyword imax-version should be deleted. b. The keyword imax-version should then be blocked from future use. 3. drew-cordeiro (41 titles) This keyword has been used for titles directed by a person named Drew Cordeiro. That sort of info does not belong in keywords. a. All instances of the keyword drew-cordeiro should be deleted. b. The keyword drew-cordeiro should then be blocked from future use. 4. "time-span" keywords The "time-span" keywords should be spelled "timespan" instead of "time-span." Accordingly, the following mergers and auto-conversions should be made. a. Merge and auto-convert these keywords in the direction of the arrows: one-day --> one-day-time-span --> one-day-timespan Please note that this will require redirecting "one-day," which correctly auto-converts to "one-day-time-span," and changing that to instead convert to "one-day-timespan." More info here. b. Merge and auto-convert these keywords in the direction of the arrows: one-night (325 titles) --> one-night-timeframe (1 title) --> one-night-time-span (52 titles) --> one-night-timespan (2 titles)
