Hello, I have a speed problem with a quite simple query (2 flwor nested) on the database below. (almost 20.000 ms !!!) The great number of docs (1200) seems to slow down the database. But the resulting database is quite small (689kB) so I'm really disappointed... If someone has an idea, it would be nice... P.S. : I tried OPTIMIZE, CREATE INDEX... Nothing will work... Thank you in advance. JMA
