Lucene.net problem with wildcard search

I have a worker service that writes data into a lucene database. I have tried different analyzers all have the same problem. (the problem is most likely in my search code)

//  var analyzer = new KeywordAnalyzer();
//  var analyzer = new WhitespaceAnalyzer(luceneVersion);
    var analyzer = new SimpleAnalyzer(luceneVersion);
//  var analyzer = new StandardAnalyzer(luceneVersion);

//  var analyzer = new KeywordAnalyzer();
//  var analyzer = new WhitespaceAnalyzer(luceneVersion);
    var analyzer = new SimpleAnalyzer(luceneVersion);
//  var analyzer = new StandardAnalyzer(luceneVersion);

Client code:

   var filenameQuery = new WildcardQuery(new Term(DocProp.Filename, "*" + SearchFor.ToLowerInvariant() ));
        filenameQuery.Boost = 2.0f;
        var filenameQuery2 = new WildcardQuery(new Term(DocProp.Filename,  SearchFor.ToLowerInvariant()+"*"  ));
        filenameQuery2.Boost = 2.0f;
        var filenameQuery3 = new WildcardQuery(new Term(DocProp.Filename,"*"+  SearchFor.ToLowerInvariant()+"*"  ));
        filenameQuery3.Boost = 2.0f;
        var filenameQuery4 = new TermQuery(new Term(DocProp.Filename,  SearchFor.ToLowerInvariant()  ));
        filenameQuery4.Boost = 2.0f;
        
        var filePathQuery = new TermQuery(new Term(DocProp.Path,   SearchFor.ToLowerInvariant()  ));
        
        var contentQuery = new TermQuery(new Term(DocProp.Content ,  SearchFor.ToLowerInvariant()));
        var query = new BooleanQuery();
        query.Add(filenameQuery,Occur.SHOULD);
        query.Add(filenameQuery2,Occur.SHOULD);
        query.Add(filenameQuery3,Occur.SHOULD);
        query.Add(filenameQuery4,Occur.SHOULD);
        query.Add(filePathQuery,Occur.SHOULD);
        query.Add(contentQuery,Occur.SHOULD);

   var filenameQuery = new WildcardQuery(new Term(DocProp.Filename, "*" + SearchFor.ToLowerInvariant() ));
        filenameQuery.Boost = 2.0f;
        var filenameQuery2 = new WildcardQuery(new Term(DocProp.Filename,  SearchFor.ToLowerInvariant()+"*"  ));
        filenameQuery2.Boost = 2.0f;
        var filenameQuery3 = new WildcardQuery(new Term(DocProp.Filename,"*"+  SearchFor.ToLowerInvariant()+"*"  ));
        filenameQuery3.Boost = 2.0f;
        var filenameQuery4 = new TermQuery(new Term(DocProp.Filename,  SearchFor.ToLowerInvariant()  ));
        filenameQuery4.Boost = 2.0f;
        
        var filePathQuery = new TermQuery(new Term(DocProp.Path,   SearchFor.ToLowerInvariant()  ));
        
        var contentQuery = new TermQuery(new Term(DocProp.Content ,  SearchFor.ToLowerInvariant()));
        var query = new BooleanQuery();
        query.Add(filenameQuery,Occur.SHOULD);
        query.Add(filenameQuery2,Occur.SHOULD);
        query.Add(filenameQuery3,Occur.SHOULD);
        query.Add(filenameQuery4,Occur.SHOULD);
        query.Add(filePathQuery,Occur.SHOULD);
        query.Add(contentQuery,Occur.SHOULD);

An example filename that I search for is "Skype" These searches give the correct result: ky kyp kype These search do not give any result (all starting with the first letter) Sk Sky Skyp Skype When debugging I can see that the variable "SearchFor" is correct and not truncated.

Reference base in different project/dll

I want to pass "base" to a function in a different dll but I can't seem to find the correct syntax. I have tried with (Application base) but can't access CreateWindow

namespace NameOfApp
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();
            MainPage = new AppShell();
        }

        protected override Window CreateWindow(IActivationState activationState)
        {
            //this should be handled by the other DLL
             var window = base.CreateWindow(activationState);
            //

           return DifferentDLL.SetCustomSize(base);
        }
}
}

namespace NameOfApp
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();
            MainPage = new AppShell();
        }

        protected override Window CreateWindow(IActivationState activationState)
        {
            //this should be handled by the other DLL
             var window = base.CreateWindow(activationState);
            //

           return DifferentDLL.SetCustomSize(base);
        }
}
}

How to change the icon for Android in a Maui/Blazor application?

Net 7.0, latest visual studio preview. I have a simple (beginner) one page Maui/Blazor app that is working fine with the default icon and default splash screen. (both windows and android with emulator and a real device connected with USB cable) I have created a custom icon and changed the project file <MauiIcon Include="Resources\AppIcon\coaster.png" /> This works on windows, but android gives an error: invalid file path '...Debug\net7.0-android\res\appicon\coaster.png'. I have tried to create new folders under android/resources, but I can't get it to compile. The default .svg icon works without a problem. Any hints?
