Examples
This example is based on the Sakila sample index from the introduction. The attributes include a field 'recommended_by_friends' which is set to false as default. We will use the SetOverrides() method to dynamically overwrite this value for a query. We then use this attribute in a sort by expression, so that films which have been recommended by friends of the user doing the search, will appear at the top of the list.
Copy
SphinxAttributeOverride<SphinxBoolean> attributeOverride = new SphinxAttributeOverride<SphinxBoolean>("recommended_by_friends");
attributeOverride.AddOverrideValue(743, true); //Normally this value would be retrieved from somewhere else

SphinxClient sphinxClient = new SphinxClient();
sphinxClient.SearchOptions.SetOverride(attributeOverride);
sphinxClient.SearchOptions.SortMode = SphinxSortMode.Expression;
sphinxClient.SearchOptions.SortBy = "@weight + (recommended_by_friends * 1000)";

SphinxSearchResult searchResult = sphinxClient.Query("room", "sakila");

foreach (SphinxMatch sphinxMatch in searchResult.Matches)
{
    Console.WriteLine(sphinxMatch);
}
