Subject Re: Additional information from external database

There really isn't a _Tika_ database connector, Tika parses the
structured files. A typical jdbc connector can connect to a DB. You
might be thinking of Data Import Handler (DIH).

Here's a program that both uses Tika and connects to a DB that might
give you a hint. It uses an older version of Solr, but should be
fairly easily modifiable.
