createIndex() call after dropIndex() is not creating persistent index data

[anidotnet]

dropIndex() call is deleting the index meta map and createIndex() call should create the index meta map before creating an index.

Also, please note that empty strings ("") against the find method will also cause the same error as above:

org.dizitart.no2.exceptions.IndexingException: NO2.5001: name is not indexed
