Re: [basex-talk] seeking for a document in a collection with a million documents is very slow

Hi Fabrice,

yes, the document index is updated with each updating command. If you perform numerous updates, you may get better performance by switching AUTOFLUSH off [1]. Another alternative to speed up multiple update operations is to use XQuery for updates. Due to the pending update list semantics, however, It will require more main memory.

Dear all,

From what I read in the documentation, My problem seems to be related to the update of the resource index.

Is this index updated after each add/replace/delete command, Or at the end of the commands’ list ?

Last, could you please tell me if replace is equivalent to delete+add ?

Best, Fabrice
