I have the same problems, I pretty much never use search in this site anymore, I prefer to use Google.
Same here, I wonder what is the best practices in implementing search and pagination in seam or in other framework overall.
In the beginning I couldn't visit this site at all when JS was enabled in Opera.
I used to turn it off, but it seems to work now.
And yes, Im having the same performance issues with page rendering and searches.
The searches are slow, probably due to usage of EntityQuery which uses SQL like statements. This could be improved with Hibernate Search.
Same problems for me - missing search results.
