Creating Examine queries without specifying fields.

In a bid to make a generic method for handling Examine queries I have created the following method.

    /// <summary>
    /// Searches the examine index to search for nodes containing the given term.
    /// </summary>
    /// <param name="query">
    /// The query to search for.
    /// </param>
    /// <param name="fields">
    /// A list of fields within a node to search.
    /// </param>
    /// <param name="searchProvider">
    /// The search provider.
    /// </param>
    /// <param name="searchType">
    /// The search type .
    /// </param>
    /// <param name="booleanOperation">
    /// The Boolean operation which determines what kind of operators to
    /// apply to the search.
    /// Defaults to OR.
    /// </param>
    /// <returns>
    /// The <see cref="ISearchResults"/> containing the search results.
    /// </returns>
    public static ISearchResults Investigate(string query,
        IEnumerable<string> fields, string searchProvider, 
        SearchType searchType, 
        BooleanOperation booleanOperation = BooleanOperation.Or)
    {
        ISearchResults results = null;

        if (!string.IsNullOrWhiteSpace(query))
        {
            // Create a search provider.
            BaseSearchProvider baseSearchProvider =
            ExamineManager.Instance.SearchProviderCollection[searchProvider];

            ISearchCriteria criteria =                      
           baseSearchProvider.CreateSearchCriteria(searchType.ToDescription(),
                                    booleanOperation)
                             .GroupedOr(fields, query.Fuzzy().Value)
                             .Compile();

            results = baseSearchProvider.Search(criteria);
        }

        return results;
    }

SearchType is an enum representing the UmbracoExamine.IndexTypes static class which cannot be passed as a constrained parameter, (Incidentally, why isn't that class an enum as it acts like one?)

My issue is this: In the config files I can specifically set which fields to index for my doctypes which allows me to constrain my index to the bare minimum. I would expect then to be able to pass just my query to the instance of ISearchCriteria without having to specify again which fields to search within and instead searches in all indexed fields.

Something like:

ISearchCriteria criteria =                      
           baseSearchProvider.CreateSearchCriteria(searchType.ToDescription(),
                                    booleanOperation)
                             .Query(query.Fuzzy().Value)
                             .Compile();

            results = baseSearchProvider.Search(criteria);

Unfortunately I cannot find anything to allow me to do that. Is there something obvious I have missed?

For some reason there is no intellisense for many of the fluent api methods so I am coding blind.
