2.1.14.2.4.5 SCORE() predicate function
BNF grammar structure: SCORE ()
Usage:
This is a predicate function that encapsulates the full-text search capability that MAY be provided
by a repository. (See previous section.)
Inputs:
No inputs MUST be provided for this predicate function.
Return value:
The SCORE() predicate function returns a decimal value in the interval [0,1].
• A repository MUST return the value 0 if the object is considered by the repository as having
absolutely no relevance with respect to the CONTAINS() function specified in the query.
• A repository MUST return the value 1 if the object is considered by the repository as having
absolutely complete relevance with respect to the CONTAINS() function specified in the
query.
Constraints:
• The SCORE() function MUST only be used in queries that also include a CONTAINS() predicate
function.
• The SCORE() function MUST only be used in the SELECT clause of a query. It MUST NOT
be used in the WHERE clause or in the ORDER BY clause.
• An alias column name defined for the SCORE() function call in the SELECT clause (i.e.,
SELECT SCORE() AS column_name ...) may be used in the ORDER BY clause.
• If SCORE() is included in the SELECT clause and an alias column name is not provided, then
a query name of SEARCH_SCORE is used for the query output, and the property definition id
is repository-specific.
2.1.14.2.4.6 IN_FOLDER() predicate function
BNF grammar structure: IN_FOLDER( [ , ] )
Usage:
This is a predicate function that tests whether or not a candidate object is a child-object of the
folder object identified by the given .
