 - `.find()` always requires the query on the right-hand side. Say you have a DocumentArray with one million Documents, to find one query's nearest neightbours you should write `one_million_docs.find(query)`;  
 - `.match()` assumes the query is on left-hand side. `A.match(B)` semantically means "A matches against B and save the results to A". So with `.match()` you should write `query.match(one_million_docs)`.

   - query (RHS) in `.find()` can be plain NdArray-like object or a single Document or a DocumentArray.
-  - query (lHS) in `.match()` can be either a Document or a DocumentArray.

 ##### What is the return?
   - `.find()` returns a List of DocumentArray, each of which corresponds to one element/row in the query.
   - `.match()` do not return anything. Match results are stored inside right-hand side's `.matches`.
