SEARCH_TERM_EXPANSION enumeration (searchapi.h)

  • Article

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;

SEARCH_TERM_NO_EXPANSION
Value: 0
No expansion is applied to search terms.
SEARCH_TERM_PREFIX_ALL
