Indicates wildcard options on search terms. Used by ISearchQueryHelper::get_QueryTermExpansion and ISearchQueryHelper::put_QueryTermExpansion methods.

Syntax

typedef enum _SEARCH_TERM_EXPANSION {
  SEARCH_TERM_NO_EXPANSION = 0,
  SEARCH_TERM_PREFIX_ALL,
  SEARCH_TERM_STEM_ALL
} SEARCH_TERM_EXPANSION;
