  Table 2 Request body parameter description

  Parameter	Mandatory	Type	Description
  labels	Either labels or edgeFilters is mandatory.	String	Filter criteria of the relationship type
  edgeFilters	Either labels or edgeFilters is mandatory.	String	Filter criteria, in JSONArray format. Vertices are filtered by property.
  offset	No	Integer	Start position of the request
  limit	No	Integer	Expected number of edges returned by a query
  sorts	No	Json	Result sorting property. It is in JSONArray format.

  Table 3 sorts parameter description

  Parameter	Mandatory	Type	Description
  key	Either Key or propertyName is mandatory.	String	Possible values are label and property, which indicate that labels or properties are sorted.
  propertyName	Either Key or propertyName is mandatory.	String	Property name
  orderValue	No	String	Possible values are incr and decr, which indicate ascending and descending order respectively. The default value is incr.

  Table 4 edgeFilters parameter structure

  Parameter	Mandatory	Type	Description
  propertyName	Yes	String	Property name
  predicate	Yes	String	Logical relationship. Possible values are =, <, >, <=, >=, range, has, hasNot, full_text_match, full_text_prefix, full_text_wildcard, full_text_regexp, full_text_fuzzy, and full_text_combination.
  values	No	String	Property value. When predicate is full_text_combination, values is not of the string type. For details, see the following note.
  type	No	String	Logical relationship of filter criteria. Possible values are and and or. The default value is and.

  

  When predicate is set to full_text_match, full_text_prefix, full_text_wildcard, full_text_regexp, full_text_fuzzy, or full_text_combination, the edgeFilters list can contain only one element, that is, multi-layer filters are not allowed. The labels parameter cannot be used at the same time. When predicate is full_text_combination, set the outermost propertyName to propertyName. In this case, the values parameter is not a simple string list. Each element of the values list has two members: propertyName and value. To use the full-text index, you need to call the API for creating a full-text index first.
