[Xapian-discuss] Closing a DB

[Benny Chan]

I was actually having this similar issue today as well (but using PHP).
Inside a loop, I open certain databases based on a variable, which could
have a re-occuring value. On those occasions that the value re-occurs, it
tries to create a new XapianWriteableDatabase object with that value again
but fails and throws an exception saying there is already a lock on that
database. I was thinking that I needed a way to close the database before
the last lines of the loop.

Anyone know the proper way to close a database?
