I like the new interface and filters in Search but it seems less wide-ranging (almost picky) in successful search terms and wildcard asterisks are now most useful, e.g. UU* returns UUAcrobat amongst the other results, but UUA returns the dreaded looking glass search not found. Filters are nice so UI is improved but functionality has changed.
Separating the acronym from rest of page name helps but was not needed on 6.9
