removeFromIndexes() is really slow

[Timo Boehme <ti...@ontochem.com>]

Hi,

deleting a large number of annotations from index via
Annotation.removeFromIndexes() takes a very long time (e.g. 200.000 out
of 700.000 took 9 minutes - normally I would expect this operation to be
finished after a couple of seconds).
Is there another possibility to do a 'bulk deletion' or clearing and
recreating an index?

Well,

May be I could add a bug in jira for that?

SimpleServer: missing doc describing service spec

[Olivier Terrier <ol...@temis.com>]

Hi all
The SimpleServer is a great contribution, unfortunately, the
documentation is quite incomplete.
In particular there is now (even basic) guidelines on how to write a
result spec xml file to customize the output.
Even a simple readme file would be of great help

Thanks in advance

The whole implementation is geared towards adding
annotations, not deleting them.  Yes, removing
annotations from indexes is slow.

Try removing the annotations in reverse order.  From
knowing the implementation, I suspect that would go
faster.

No, but it would probably be easy to implement an
operation to drop an entire index, or to drop the
index for specific types.
