Rick
I have the following collection based on your first note:
{
"_id" : ObjectId("5253b7f31302e3210b53f9e1"),
"authour" : "Cool Author",
"chapter" : [{
"chapterid" : 1,
"sections" : [ ],
"title" : "Chap A"
}, {
"chapterid" : 2,
"sections" : [ ],
"title" : "Chap B"
}],
"title" : "My Book"
}
And running this query :
db.arrayTest.find(
{'chapter.chapterid' : 1 },
{'chapter' : { $elemMatch : { 'chapterid' : 1 } } }
)
returns me
{
"_id" : ObjectId("5253b7f31302e3210b53f9e1"),
"chapter" : [{
"chapterid" : 1,
"sections" : [ ],
"title" : "Chap A"
}]
}
Is this what you where looking for?

Any insight would be helpful. Don't know of any other resources to
ask. The capability does exist in mongodb from many approaches but
it's not working for me through openbd.
Anyone?

I'm using the latest mongodb and openbd.
However, while I can query and get back the entire BOOK data, I cannot
seem to limit the query to only get back 1 chapter at a time. I am
absolute that mongodb supports it but when I try the examples from the
mongodb site to access the array to only return a chapter, it will not
return it alone. I've gone through all of the ways that mongodb's
docs says that the array can be accessed.
I've tried to see if there was a new mongodb jar available to update
openbd and I see that the latest openbd is using the latest mongodb jar.
Stuck!

book = {
title = "My Book",
author = "Cool Author",
chapters = *chapters*
};
