Flush Index

Hello

I am trying to synchronize my code with the index for a unit test.
It seems to be that I can not use the QueryManager immediately after adding
a node to search this node.
Is this right? 
The MultiIndex is running as a background thread and I can tell him how
often it should run. 
But can I synchronize it?

Thanks
Juergen

Hi,

committed changes are immediately searchable by any session.

can you please be more specific about what worker-thread you mean?

Thank you Marcel.

And after commit? Do I have to wait until the Worker-Thread is finished?

BTW:
Is this a standard or a jackrabbit 'feature'?

Thanks
Juergen

no, this is not possible. jackrabbit only allows you to execute queries against
committed changes.

Hello Marcel,

I don't want to commit this changes.
I am using Springs AbstractTransactionalSpringContextTests to rollback my
changes after running.
So I need to use the index inside the same transaction. Isn't this possible?

Thanks
Juergen

the query manager will always execute the query against all persisted changes.
can you please double check that you called save() and committed the transaction
(if there is one) before you execute the query?

what exactly do you mean with 'synchronize it'?
