RAMDirectory Lucene

Question

I am trying to index text files and using the RAMDirectory for fast indexing and was wondering if there is a way to clear the previous RAMDirectory to prevent duplicates?

Answer 1

Not sure what you mean by "clear the previous RAMDirectory", but you can overwrite the previous index at the RAMDir by string the create flag to true. This would create a new index at the location for the constructor call.

IndexWriter(Directory d, Analyzer a, boolean create, IndexWriter.MaxFieldLength mfl) 

Constructs an IndexWriter for the index in d.
