p is an argument to search.pattern,
depth: int, skip: function, keys: (str...) -> r: generator
this is a generator over keys k such that p == self[k]
if keys is specified, then depth and skip are ignored, and the search
is performed only over keys. Otherwise, the search is performed over
self.iter(depth, skip)
if tops is true, and p can match Docs, then the subkeys of any subdoc that
matches p will not be searched. This will only work as expected if "keys"
is not set.
If setns is True, then p should be a search.Pattern instance. This function
will assign self to the key "doc" in p.ns, and call p.setup before searching.
Note that this is a generator, not a function that returns a collection.
To get the list of hits, use [k for k in self.find(...)]
(this idiom is bound to self.findall)
To get the first hit, use:
try:
v = self.find.next()
except StopIteration:
#nothing found
v = None
