~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/11/05 - singhan: compiler/include/core.h,1.48
XQuery full-text search support initial version!
This initial version provides support to
-ftcontains keyword,
e.g., for $f in doc("menu.xml")//food[./name ftcontains "Belgian Waffles"]
return $f
The above query will return all the food nodes that has some relevancy over
"Belgian Waffles"
-initial score variable support
e.g., for $f score $s in doc("menu.xml")//food[./name ftcontains "Belgian
Waffles"]
return $s
The above query will return the relevancy score of all the matched food
nodes, however since its an initial version, the support to this score variable
is very limited.
