FUNCTION_RESTRICTION_PREFIX

public static final String FUNCTION_RESTRICTION_PREFIX

The prefix for restrictions for function-based indexes, for example upper(propertyName). Syntax: "function*expression". In order to support all kinds of expressions in the future (including nested expressions and so on), the format for the expression is written in the Polish notation (the RPN, reversed), with "*" as delimiter (as property names may not contain "*"), and "@" in front of each property name to distinguish between property names and functions. Literals are quoted. Examples: The expression "lower(lastName)" is converted to "function*lower @ lastName". The expression "lower(lastName)" is converted to "lower(upper(lastName))" is converted to "function*lower*upper* @lastName". The condition "firstName+' '+lastName = 'Tim Cook'" would be "function*+*+ @ firstName*' ' @lastName.
