I'm new to PP. What I want to achieve is a very simple script showing me that PP can use lucene index-DB-files which where generated outside PP.

I've got a java-program using the Lius/Lucene engine to generate index-DBs. When I create a protocol with a Search-Text-Database-component connected to a View-Search-Results-component I get this error: "There is no readable Text DB directory found at...". I've pointed the component to the correct directory. The index-DB can easily be opened by Luke.

When I create an index-DB with PP, this works fine to search. When I looked at the PP-index I noticed an xml-file pointing to an other xml-file with field definitions. I’ve tried to mimic this with my index-DB and created such an xml-file as well including the descriptions of the fields. But still I get this error...

Any idea what I can do to get this working?
Thanks.
