    Examine - missing Fuzzy & Boost?

    Extending Umbraco

    Trying to use Fuzzy and Boost as follows

    var test = searchCriteria.Field("nodeName", "hello".Fuzzy(0.8)).Complie();

    But keep getting missing reference error

    'string' does not contain a definition for 'Fuzzy' and no extension method 'Fuzzy' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)

    Using Umbraco 4.7.1.Beta - any ideas?

    I ran into this same problem, been scratching my head for a while now, finally found the namespace to include;

        @using Examine.LuceneEngine.SearchCriteria;

    From the code I suspect, like me, you were looking at this article,

        http://umbraco.com/follow-us/blog-archive/2011/9/16/examining-examine.aspx

    The code in that article has a small but very important typo and you'll get a message similar to;

     error CS1928: 'string' does not contain a definition for 'Fuzzy' and the
 best extension method overload 'Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.Fuzzy(string,
 float)' has some invalid arguments

    The 0.8 will default to a double in c# so you're line of code should read;

        var test = searchCriteria.Field("nodeName", "hello".Fuzzy(0.8f)).Complie();

    What about fuzzy AND boost.  That was the original question.  Seems lots of problems and no solutions being posted.

    Fuzzy and boost are extension methods.  Make sure you are including the correct namespaces.

    @using Examine;
    @using Examine.SearchCriteria;
    @using Examine.LuceneEngine.SearchCriteria;    <-  This one has Fuzzy / Boost extension methods

    I have that one already:

    using Examine;
using Examine.LuceneEngine.SearchCriteria;

    I can get one or the other but not both, Fuzzy AND Boost.

    @Connie, sorry, I misunderstood.  The original question was about a missing reference.

    After doing some debugging, I think I can give you a somewhat definitive answer that using both Fuzzy AND Boost on the same search phrase is _not_ possible.

    The type that Fuzzy and Boost return is "Examine.LuceneEngine.SearchCriteria.ExamineValue"

    That object has three members:

    • Value = "The string we are searching for"
    • Level = A float between 0 and 1
    • Examineness = This is a Enumeration

            Fuzzy = 0,
            SimpleWildcard = 1,
            ComplexWildcard = 2,
            Explicit = 3,
            Escaped = 4,
            Boosted = 5,
            Proximity = 6,

    Examineness can only be set to a single enum value, so you can pick one and only one enum value for each instance of IExamineValue.
