15.4 Refining Queries by Using Facets As Filters

The facet implementation now supports CONTAINS queries with the standard set of database comparison operators available for SDATA. The following example is based on the ‘name’ varchar2 section. When you use it with numbers, do not use quotation marks around the numeric term to be searched.

contains (text, 'SDATA(sec01 = "run")', 1) > 0
contains (text, 'SDATA(sec01 > "run")', 1) > 0
contains (text, 'SDATA(sec01 >= "run")', 1) > 0
contains (text, 'SDATA(sec01 < "run")', 1) > 0
contains (text, 'SDATA(sec01 <= "run")', 1) > 0
contains (text, 'SDATA(sec01 <> "run")', 1) > 0
contains (text, 'SDATA(sec01 != "run")', 1) > 0
contains (text, 'SDATA(sec01 between "run1" and "run2")', 1) > 0
contains (text, 'SDATA(sec01 not between "run1" and "run2")', 1) > 0
contains (text, 'SDATA(sec01 is null)', 1) > 0
contains (text, 'SDATA(sec01 is not null)', 1) > 0
contains (text, 'SDATA(sec01 like "%run")', 1) > 0
contains (text, 'SDATA(sec01 like "run%")', 1) > 0
contains (text, 'SDATA(sec01 like "%run%")', 1) > 0
contains (text, 'SDATA(sec01 not like "%run")', 1) > 0
contains (text, 'SDATA(sec01 not like "run%")', 1) > 0
contains (text, 'SDATA(sec01 not like "%run%")', 1) > 0

contains (text, 'SDATA(sec02 = 9)', 1) > 0
contains (text, 'SDATA(sec02 < 10)', 1) > 0
contains (text, 'SDATA(sec02 between 2 and  20)', 1) > 0

The comparison operators behave according to the current optimized_for search SDATA behavior for the various data types.
