[basex-talk] Index auto update

Hello, I'm a little bit confused with indexes auto update mechanism. Having created a DB with UPDINDEX=true, and after inserting nodes, 'info database' shows : Indexes Up-to-date: false Text Index: ON Attribute Index: ON Full-Text Index: OFF whereas UPDINDEX=true. After issuing 'optimize', Up-to-date come back to true and FT index to ON. Does this mean index are not automatically updated if 'optimize' is not run? I use BaseX73-20120528.232116.jar Is there any comprehensive documentation about index update mechanism? Thank-you, Gilles.
