If you are using the KeywordQuery class, here is a snippet that should get you what you want:

    // instantiate a KeywordQuery object first

    keywordQuery.SimilarType = SimilarType.Find;

    // I'm just using some example values here to ilustrate the usage of the SimilarTo property.    
    keywordQuery.SimilarTo ="[social services, 1][interior renovations, 1][ministry, 0.707107]";                
    keywordQuery.SortSimilar = true;                        
    keywordQuery.QueryText = "projectnumber=12345";

    // perform the query
    ResultTableCollection keywordQuerySearchResults = keywordQuery.Execute();
