hibernate version
3.2.6 GA
3.0.0 GA (hibernate search)


Hi I am using index provider to do search. Now if i index my domain using batch process, where should i copy the indexes to, so that i can use it for web application in tomcat?

use the configuration property

to define the root of your indexes.
Then you need to put the index in a subdirectory corresponding to the name attribute of @Indexed
Or a simpler way just define the indexBase property and start it: H.Search will create the directory structure it expects for you, then you shut it down and replace it's empty index with yours.

sorry I am using RAMDirectoryProvider.

If you need to copy the index your only option is to use the FSDirectoryProvider,
there currently is no option to start a RAMDirectoryProvider from file;
Consider that when using the RAMDirectoryProvider you are going to use the limited JVM memory, but when using hte FS-dp the memory management is delegated to your OS, also the caching of these could be very good and I still have to see a good benchmark demonstrating the ram version being consistently faster than the file based version.

If you still have a good reason to need it, we could ask for it as a new feature; explaining a good reason to ask for it would greatly enhance your chances to get it done, or provide a patch, I could help you it should be simple.
