Hi Paolo,
You can find a description of it here :
http://www.3liz.com/blog/rldhont/index.php?post/2012/11/06/Spatial-operators-in-QGIS-expression
You can do this type of expression :
intersects( $geometry, geomFromWKT( 'LINESTRING(765145.88 6274561.22,
776031.67 6284189.52)' ) )
I made it for WFS QGIS-Server
Regards,
René-Luc D'Hont

Hi all.
In the Field Calculator there are, among the expressions, a series
of spatial
operators (touches, intersects, etc.), but I cannot figure out how
to use them. They
make sense as operators across layers, but I do not see how to use
them within the
same layer.
Any hint?
Thanks.
