I imported some sort-of sloppy XML data into a Mongo database. Each Document has nested sub-documents to a depth of around 5-10. I would like to find() documents that have a particular value of a particular field, where the field may appear at any depth in the sub-documents (and may appear multiple times).
I am currently pulling each Document into Python and then searching that dictionary, but it would be nice if I could state a filter prototype where the database would only return documents that have a particular value of the field name somewhere in their contents.
Here is an example document:
{
"foo": 1,
"bar": 2,
"find-this": "Yes!",
"stuff": {
"baz": 3,
"gobble": [
"wibble",
"wobble",
{
"all-fall-down": 4,
"find-this": "please find me"
}
],
"plugh": {
"plove": {
"find-this": "Here too!"
}
}
}
}
So, I'd like to find documents that have a "find-this" field, and (if possible) to be able to find documents that have a particular value of a "find-this" field.
