      Description

      Filter expression restrictions where introduced in ODATA-816 to express restricted filter capabilities on individual properties that can only be used in equality comparison or interval comparison.

      Similar to MultiValue being multiple SingleValues joined by OR, MultiRange is multiple SingleRanges joined by OR, with a slight generalization: in addition to closed intervals also half-open and open intervals are allowed, as well as degenerate intervals (closed intervals with identical lower and upper boundary can be expressed simply via EQ).

      This means that MultiRange subsumes SingleRange as well as MultiValue and SingleValue.

      For string-valued properties this can be extended to include multiple SearchExpressions: MultiRangeOrSearchExpression, allowing to OR zero or more startswith, endswith, or contains functions comparing the property to a string literal.

      These expressions are all fairly simple, including a property, a literal value, and at most one level of parentheses. They represent expressions that can be constructed by typical "extended search" forms that allow to pick the comparison operator and enter the comparison value (or two values for "between").
