You can enable snippets for a particular attribute on a per query
basis using the
SearchFilter element in the Conversation Web Service.
Setting the
EnableSnippeting attribute to
true in the
SearchFilter enables snippeting per query, for the
specified property. The
SnippetLength attribute sets the length of the
snippet; the search term specifies the snippet term:
<ns:Request>
<ns:State/>
<ns:Operator xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ns="http://www.endeca.com/MDEX/conversation/1/0" xsi:type="ns:SearchOperator">
<ns:SearchFilter Key="Description" EnableSnippeting="true"
SnippetLength="4">gearing</ns:SearchFilter>
</ns:Operator>
</ns:Request>
Note: Use these settings only if you need to specify snippeting
information for a single attribute for which there is no search interface
configured. These settings do not override the settings that globally enable
snippeting for members of the search interface in the
RECSEARCH_CONFIG > SEARCH_INTERFACE elements.
