This broadens the typeahead datasource search for repos. Before this patch a repository named "Alligator Simulator" would not be found with the search string "simu...". This is patched with the ferret engine search and indexing features.

See T15583

Create repositories with titles with 2 or more words. Search for these repos with the global typeahead search. The search term should begin with the second/third/n-th word of the repo title.
