changes to the filter preset

Teiltreffer funktionieren, z. B.:
Rechen findet Rechenschiffchen
ein Fragment aus der Beschreibung findet den Artikel ebenfalls
Groß-/Kleinschreibung spielt keine Rolle
Die zusätzliche lokale ID-Filterung wurde entfernt, da sie Treffer teilweise wieder ausgeblendet hat.
Die Suche verwendet nun die serverseitige MongoDB-Abfrage mit regulären Teiltreffern.
