Yobi, there isn't currently. If you had an index, you can display searches of that in the webadmin (potentially getting all matching items). I hope we soon can merge the console and the search bar, making the tabular or visual view optional outcomes of arbitrary searches, Gremlin or Cypher

You probably need to create a custom analyzer using one of Lucene's collation filters (which you will provide as a parameter to the Neo4J index creation method). Unfortunately, you can't apply a new analyzer after the fact. I think you'll need to delete and regenerate the index. Lucene has
