Specifying No Intersections (``OR'')

Using this intersection quantity model, what is commonly understood to be an ``OR'' search is any search which requires no (zero) intersections at all. In an ``or'' search, any occurrence of any item listed qualifies as a hit; the item need not intersect with any other item.

Designate an ``or'' search using the same intersection quantity syntax, where zero (0) indicates no intersections are required (@0):

Example:

     WHERE BODY LIKE '~alcohol ~sweets ~consumption @0'

In addition to the hits listed above for a higher number of intersections, the following 0 intersection hits would be found, due to the presence of only one item (a or b or c) required:

  ~alcohol @0
     Every person licensed to sell LIQUOR, wine or beer or mixed
     beverages in the city under the Alcoholic Beverage Code
     shall ...

  ~sweets @0
     An establishment preparing and selling at retail on the
     premises, cakes, pastry, CANDIES, breads and similar food
     items.

  ~consumption @0
     To regulate the disposal and prohibit the BURNING of garbage
     and trash; ...

All such items are considered permuted, at intersection number zero (0).
