Create fulltext index for a View

I created an attribute view with a column consisting of two concatenated strings. My aim is to search this view with fuzzy search.

First I got this error:

Failed to execute action: Error: $.hdb.Connection.executeQuery: SQL error. NR: 7, ERROR: feature not supported: columns of (var)binary and LOB types need fulltext index: line 1 col 187 (at pos 186) at ptime/query/checker/check_expr.cc:5713

Afterwards I tried to create the mentioned fulltext Index with the following query:

CREATE FULLTEXT INDEX DISPLAYNAMEINDEX ON "data::UserSearchView" ( DISPLAYNAME )

Resulting in this error:

Could not execute 'CREATE FULLTEXT INDEX DISPLAYNAMEINDEX ON "data::UserSearchView" ( DISPLAYNAME )'

SAP DBTech JDBC: [7]: feature not supported: cannot create index on view: line 1 col 43 (at pos 42)

Is it somehow possible to create the index anyways? And/or what do I need to do to use fuzzy search in this scenario?
