The query algorithm begins at the starting item set, and recursively descends to its children and their children. At each item set, the algorithm collects index items according to other parameters and returns some number of those. The collection of index items is controlled by the following attribute:
<query recurseDocuments="mode
"
A mode value of on
or true
means that index items may be collected from child item sets. A mode value of off
or false
means that index items may only be collected from the immediate item set, excluding any from child sets. A mode value of empty
means the same as off
, unless the immediate item set has no documents. The default value is off
.
