Any & All
Within a Search the user can set additional constraints for selected values: in the Properties and Value Pairs box there is a special row with few radio buttons indicating the Any and All options.
In logical terms, Any means disjunction (logical OR) within a constraint.
Selecting Any the search results have all possible matches of selected items: this means that a result (row) is shown if it satisfy at least one of the selected values.
By contrast, All means conjunction (logical AND) within a constraint.
Selecting All the search results have only those matches that have all the selected items: this means that a result (row) is shown if it satisfy ALL selected values.
Suppose a user clicks on Language in the Show line and selects the following property_value pairs (in the constraint box): Attributive Adjective Agreement:Yes and Auxiliary Selection:Yes.
If All is specified, this search will find the set of languages that have agreement with Attributive Adjectives AND for which the property of Auxiliary Selection holds.
If a user had clicked Any instead, then the search would yield the set of languages that have Agreement with Attributive Adjectives OR for which the property of Auxiliary Selection* holds (or both).
