Previous value: -"Filter providers by the practice size they best serve."New value: +"Filter providers by the practice size they best serve, on the directory's one closed vocabulary: Solo, Small, Mid-size, Large, All. The filter reads the extracted size where one exists and the listing's stated fit otherwise; a listing stating 'Solo/Small' answers both Solo and Small. 'All' means the vendor serves every size -- on listings that were never extracted it is also the default, so it narrows results little."
