[UCSD Request] Contributors show up in autofill box, but yield 0 results [SIDASH-175]

[NyanHelsing]

There are multiple instances where a Contributor is listed in the autofill box on a secondary search page, but when selecting it, the search yields 0 results. Some examples:

• From https://birdbrained.github.io/share-analytics/#/search?publishers=64070-DBB-0DD, type "b" in Contributors box and select "Brett Cannon" when it appears.
• From https://birdbrained.github.io/share-analytics/#/search?publishers=64070-DBB-0DD, type "B" in Contributors box (note: the options are different from the options that appear when using a lower case b) and select "Bridget Dixon" (https://birdbrained.github.io/share-analytics/#/search?contributors=64245-140-03C&publishers=64070-DBB-0DD). Not only do we get 0 results, but the facet displays the "Contributors" label without a value ("Bridget Dixon").
• From https://birdbrained.github.io/share-analytics/#/search?publishers=64070-DBB-0DD, type "a" in Contributors and select "Alexandra Calmy" (https://birdbrained.github.io/share-analytics/#/search?contributors=6421E-36E-CE9&publishers=64070-DBB-0DD).
