jina.drivers.querylang.sort

class jina.drivers.querylang.sort.SortQL(field, reverse=False, traversal_paths=('c', ), *args, **kwargs)

Bases: jina.drivers.QuerySetReader, jina.drivers.BaseRecursiveDriver

Sorts the incoming of the documents by the value of a given field. It can also work in reverse mode

Example:: - !ReduceAllDriver

with:

traversal_paths: [‘m’]

• !SortQL

  with:

  reverse: true field: ‘score__value’ traversal_paths: [‘m’]

• !SliceQL

  with:

  start: 0 end: 50 traversal_paths: [‘m’]

SortQL will ensure that only the documents are sorted by the score value before slicing the first top 50 documents

Parameters

• field (str) – the value of the field drives the sort of the iterable docs

• reverse (bool) – sort the value from big to small
