Mongo query on cursor (pymongo)
Suppose that col
is a collection. I want to perform a query like this one:
filter1 = col.find("field1": valueX, "field2": valueY)
Now, I don't really need filter1
, I need
filter2 = col.find("field1": valueX, "field2": valueY, "field3": valueZ)
filter3 = col.find("field1": valueX, "field2": valueY, "field4": valueW)
This of course search twice the conditions "field1": valueX, "field2": valueY
. I want to do something like
filter2 = filter1.find("field3": valueZ)
filter3 = filter1.find("field4": valueW)
in order to optimize the query. How can I achieve this?
