/*
* STRUCT: SE_Search_Rule
*
* Used to specify a single rule in a set of rules, which can then
* be used to create a search filter. A search filter uses its
* associated set of rules to filter objects, so that only objects
* that pass the rules will be returned to the user (see SE_Iterator,
* SE_Search_Filter for more details.)
*
* A single search rule by itself is useless. A set of search rules
* is specified using an array of type SE_Search_Rule, filled in
* with a well-formed postfix notation expression, ending with an
* SE_Search_Rule entry with a rule_type value of SE_SEARCHRULETYP_END. The
* sequence of SE_Search_Rule forms an RPN logic evaluation stack.
*
* Macros are provided (which see) that allow a somewhat more
* readable pre-fix notation to be used when initializing
* arrays of SE_Search_Rule in variable declarations. A static
* search (a search whose conditions are known at compile time) can
* easily be specified by taking advantage of the search macros (see
* the examples, given in the comments preceding the search macros).
*
* A dynamically created search, on the other hand, requires the user to
* create a rules array and fill in the array with a well-formed postfix
* notation expression, ending with an SE_Search_Rule entry with a
* rule_type value of SE_SEARCHRULETYP_END.
