    'Returns suggestions that are fully verified USPS addresses.'
    'Uses fuzzy logic during searching to:'
      - 'Allow for missing directionals and street suffixes'
      - 'Allow substitution of street suffixes and secondary designators (E.g. ST is accepted for AVE; APT is accepted for UNIT, etc.)'
      - 'Allow full or partial spelling of street suffixes and secondary designators (E.g. ST can be spelled as STR or STREET and still match)'
    'Filters and preferences allow for multiple cities in a single state.'
    'Provides filter keywords for commons state collections such as allstates.'
    'ZIP Codes are valid filter and preference values.'
    'Allows searching on alternate cities.'
