Gets the value that specifies how query terms are to be expanded.
Syntax
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.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
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.
