Filtering a long list with search bar is very slow

I have a list with up to 100 items. While filtering the list with a searchbar it takes some time for every letter. How can I speed up the search? One possible solution is to filter only after click the search button on the keyboard.

        
     
            VStack {
                SearchBar(text: $searchTerm, placeholder: "Suche")
            }
            
         
                List {
                    
                    ForEach(gesetzestextTEMPO.filter {
                        self.searchTerm.isEmpty ? true : $0.titel1.localizedCaseInsensitiveContains(searchTerm)
                            || $0.titel1.localizedCaseInsensitiveContains(searchTerm)
                            || $0.artikel.localizedCaseInsensitiveContains(searchTerm)
                            || $0.marginale.localizedCaseInsensitiveContains(searchTerm)
                            || $0.absatz0.localizedCaseInsensitiveContains(searchTerm)
                            || $0.absatz0litaz.localizedCaseInsensitiveContains(searchTerm)
                          
                        
                        })
                    { item in
                        Part13(gesetzestextTEMPO: item, searchTerm: self.$searchTerm)
                    }
                }```

Try the following:

List {
    // ...
}
.id(UUID())
