HRESULT get_QueryTermExpansion(
  [out, retval] SEARCH_TERM_EXPANSION *pExpandTerms
);

Parameters

[out, retval] pExpandTerms

Type: SEARCH_TERM_EXPANSION*

Receives a pointer to a value from the SEARCH_TERM_EXPANSION enumeration that specifies the query term expansion.

Remarks

While the SEARCH_TERM_EXPANSION enumerated type lets you specify stem expansion, Windows Search does not currently support its use with the ISearchQueryHelper interface.

Checkout the DSearch code sample to see how to create a class for a static console application to query Windows Search using the Microsoft.Search.Interop assembly for ISearchQueryHelper.
