Sets a value that specifies how query terms are to be expanded.
Type: SEARCH_TERM_EXPANSION
Value from the SEARCH_TERM_EXPANSION enumeration that specifies the search term expansion. If not set, the default value is SEARCH_TERM_PREFIX_ALL.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The ISearchQueryHelper::put_QueryTermExpansion method allows for expansion of some query terms with wildcard characters, similar to regular expression expansion.
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.
