→Full-Text Index
Text nodes can be directly accessed from the index via the XQuery function [[Database Module#db:fulltext|db:fulltext()]]. The [[Full-Text Module]] contains additional functions for retrieving index data.
=Updates=
By default, index structures are discarded after an update
operation, and their maintenance is left to the user.
After the execution of update operations, the [[Commands#OPTIMIZE|OPTIMIZE]]
command or the [[Database Module#db:optimize|db:optimize]] function can be
called to rebuild the index structures.
This way, multiple update operations will be performed faster,
as the database meta data is only updated and regenerated
once in the updating process.
As an alternative, incremental indexing can be turned on for the text
and attribute value index: the [[Options#UPDINDEX|UPDINDEX]]
option must be activated before creating a new database. Note that,
even with this option, the update of the path and fulltext index will
have to be manually triggered.
