I wonder if the full-text index is also available to attribute nodes:
Unfortunately it's not; as most queries we know are based on text nodes, we decided to skip attribute full-text requests. Note, however, that special characters, such as "[", are ignored anyway.
The full-test was activated using the console:
create index fulltext
Index created in 562.23 ms.
OPTIMIZE
Database optimized in 27349.05 ms.
SET FTINDEX
Full-Text Index: ON
Just as a hint (the documentation is very sparse on that): optimize is only needed after database updates. If FTINDEX is set to ON, all subsequent database creations will include fulltext indexing.
