Umbraco Examine Search query null value

Question

I am trying to fix my search engine. The problem is that when I search for my existing blog item, it always says

Did not match in any document

What ever I search for, it always give me that error message.

Is there any way to fix this or does my code have a problem?

@using Examine.LuceneEngine.SearchCriteria
@inherits Umbraco.Web.Macros.PartialViewMacroPage

string searchTerm = Request.QueryString["search"];
var searcher = ExamineManager.Instance.SearchProviderCollection["MySiteSearcher"];
var searchCriteria = searcher.CreateSearchCriteria();
var query = searchCriteria.Field("nodeName", searchTerm).Or().Field("bodyText", searchTerm).Compile();
var searchResults = searcher.Search(query);

@if (searchResults.Any()){
    <ul class="search-results">
        @foreach (var result in searchResults)
        {
            IPublishedContent node = Umbraco.Content(result.Fields["id"]);
            <li>
                <a href="@umbraco.library.NiceUrl(result.Id)">
                    @if (result.Fields.ContainsKey("nodeName")) {
                        @node.GetPropertyValue("blogItemTitle")
                    }
                </a>
                <p>@result.Fields["blogbodyText"]</p>
            </li>
        }
    </ul>
} else {
    <p class="error-result">
        Your search
        @if (!String.IsNullOrEmpty(searchTerm))
        {
            <strong><text>'@searchTerm'</text></strong>
        }
        did not match any documents.
    </p>
}

here's my Setting

Answer 1

A couple of things to check, firstly, check that your index is actually populating correctly. You can download the tool Luke from here (requires Java). This handy tool lets you view the contents of your index.

If you fire up Luke and point it at the index folder in /App_Data/TEMP/ExamineIndexes/MySiteSearcher it should show you how many items are in the indexer and what fields they contain. Check that a) there are documents in the index, and b) that the index is indexing the fields that you are searching on.

If everything looks OK, it could be the syntax of the search. Looking at your code, you're going to end up with the search requiring the nodeName to match the search term, with an optional match in the bodyText (the default search operator is AND, which means the first item in the query MUST always match). If you want to match in either, you'll need to set the deafult operator of the search to be or, using the following code:

var searchCriteria = searcher.CreateSearchCriteria(Examine.SearchCriteria.BooleanOperation.Or);
