Hi,

is there any way to create a new index as an alternative to an existing index and then switch to the new index after its been built? The application should use the old index until the new one is fully built and then replace it with the new one. Preferably without taking down the application.

We rebuild our index every night, and the solution is based on first purging the whole index and then rebuilding it afterwards, but another strategy that we are investigating is to leave the old index alone, build a new one and then switch to the new one without having to restart the application.

Any ideas or pointers would be appreciated.
