Hi, Moshir:
One way to solve this problem is to model the data differently: store each car
as a separate document and store the agency id in each car document so it is
easy to retrieve individual cars or all cars for an agency.
An alternative approach is to qualify the documents with the car nodes and
extract the car nodes. Something like the following (untested) code should work:
db.documents.query(
qb.where(qb.byExample({size:'small'}))
.slice(qb.extract(['/cars[size eq "small"]']))
).result(...)
For more information about extract, see:
http://docs.marklogic.com/guide/node-dev/search#id_17648
Extract paths have the same limitations as paths for range indexes:
http://docs.marklogic.com/guide/admin/range_index#id_40666
That said, modifying the model is usually the better approach in the long run.
Hoping that helps,
Erik Hennum

Hi,
I'm new to marklogic and I'm using node.js client.
I have a very simple structure already loaded to database
{
id : id of an agency,
cars : [ an array of cars ]
}
each car in the array has following properties
[
type : type of car,
size : size of car
]
I want to use the node.js client api
to query all cars with given type and/or size.
When I use
.db.documents.query(qb.byExample({size:'small'}))
it returns me all agencies with at least one small car (just guessing), but not
cars
Any help really appreciated !
