A search function that adds the value of a single context property to a search string.

You can use the following parameters:

Example:

The context named "bar" contains a property "foo" which has a value "42". Then, the search function contextProperty(property:bar.foo, field:field) will be evaluated to 'field:42'. That is, the Search Engine searches in the field named "field" for the value "42".

A search function that selects from a user's context a set of keys that fulfill a weight constraint.

You can use the following parameters:

Example:

The context object named myContext contains the properties (foo, 0.8), (bar, 0.5), (zork, 0.1). Then, the search function userKeywords(threshold:0.5, limit:-1, field:field, context:myContext) will be evaluated to field:(foo bar) and the search function userKeywords(threshold:0.5, limit:1, field:field, context:myContext) will be evaluated to field:(foo).

A search function that selects the set of customer segments the active user belongs to.

You can use the following parameters:

Example:

The context object named "myContext" contains the properties ('content:42', true), ('content:44', false), ('content:46', true). Then, the search function userSegments(field:field, context:myContext) will be evaluated to "field:(42 46)". This function is intended to be used with the user segmentation feature of CoreMedia Adaptive Personalization, which uses property keys of the form content:<segmentId> (where segmentId is the numeric content id of a customer segment) to represent segments in a user's context.
