v8 Search Exclude MediaItem

I'm using this for my searcher:

if (ExamineManager.Instance.TryGetIndex("ExternalIndex", out var index))
        {
            var searcher = index.GetSearcher();
            //var results = searcher.CreateQuery("content").NodeTypeAlias("home").And().Field("nodeName", searchTerm).Execute();
            //var results = searcher.CreateQuery().NativeQuery("+__IndexType:content +nodeName:" + searchTerm).Execute();
            //var results = searcher.CreateQuery().NativeQuery("+__IndexType:content " + searchTerm).Execute();
            var results = searcher.CreateQuery("content").ManagedQuery(searchTerm).Execute();
            if (results.Any())
            {
                <ul>
                    @foreach (var result in results)
                    {
                        if (result.Id != null)
                        {
                            var node = Umbraco.Content(result.Id);
                            <li>
                                <a href="@node.Url">@node.Name</a>
                            </li>
                        }
                    }
                </ul>
            }
            else
            {
                <p>No results found for query @searchTerm</p>
            }
        }

The results correctly include a page that contains my search term. But, it's also returning an image with my search term in its file name. How do I exclude media items from my searcher?

This works...

@if (!string.IsNullOrWhiteSpace(searchTerm)) {
        var results = Umbraco.ContentQuery.Search(searchTerm, string.Empty);
        long resultCount = results != null && results.Any() ? results.Count() : 0;
        if (resultCount > 0)
        {
            <ol>
            @foreach (var result in results)
            {
                <li><strong><a href="@result.Content.Url">@result.Content.Name</a></strong></li>
            }
            </ol>

        }
        else
        {
            <p>No search results were found for <strong>@searchTerm</strong></p>
        }

    }

Hi BH,

Using examine, it is possible to exclude media from your search.

To do this use the fluent API to add the following to your query:
```
.And().Field("__IndexType", "content")
```
This will ensure results given back are only for content.

I believe that this is what searcher.CreateQuery("content") is meant to do but there is a bug in it. You could try upgrading Examine and it might fix that issue, although I can't recall if it does or not.

I ended up using @Nik's code.

@if (!string.IsNullOrWhiteSpace(searchTerm)) {
    if (ExamineManager.Instance.TryGetIndex("ExternalIndex", out var index)){
            var searcher = index.GetSearcher();
            var results = searcher.CreateQuery("content").ManagedQuery(searchTerm).And().GroupedOr(new[] { "__NodeTypeAlias" }, new[] { "page", "home", "communities", "communityDetail", "connect", "leadership", "news", "newsItem" }).And().Field("__IndexType", "content").Execute();
            if (results.Any())
            {
                <ol class="scrollbar">
                    @foreach (var result in results)
                    {
                        if (result.Id != null)
                        {
                            var searchResult = Umbraco.Content(result.Id);
                            var searchText = (searchResult.Value("metaDescription") != null ? searchResult.Value("metaDescription") : (@searchResult.Value("CommunityDetialDescription") != null ? @searchResult.Value("CommunityDetialDescription") : string.Empty));
                            <li>                                
                                <a href="@searchResult.Url"><b>@searchResult.Name</b><br />@Helper.Trunc(searchText.ToString(), 200)</a>
                            </li>
                        }
                    }
                </ol>
            }
            else
            {
                <p>No results found for query @searchTerm</p>
            }
        }
        return;
    }
}
