jina.drivers.querylang.sort

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

Bases: jina.drivers.QuerySetReader, jina.drivers.ContextAwareRecursiveMixin, 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

param field

the value of the field drives the sort of the iterable docs

param reverse

sort the value from big to small

param traversal_paths

the traversal paths

param args

additional positional arguments which are just used for the parent initialization

param kwargs

additional key value arguments which are just used for the parent initialization

runtime: Optional[ZEDRuntime]
