Search any instance of a certain token within the text property targeted (case insensitive).

Returns:a predicate to apply in a GraphTraversal.

Supports finding words which are a within a specific distance away (case insensitive).

Example: the search expression is phrase("Hello world", 2) 
    
  
  • the inserted value "Hello world" is found
  
  • the inserted value "Hello wild world" is found
  
  • the inserted value "Hello big wild world" is found
  
  • the inserted value "Hello the big wild world" is not found
  
  • the inserted value "Goodbye world" is not found.



Params:
  • query – the string to look for in the value
  • distance – the number of terms allowed between two correct terms to find a value.
Returns:a predicate to apply in a GraphTraversal.

Supports fuzzy searches based on the Damerau-Levenshtein Distance, or Edit Distance algorithm
(case sensitive).

Example: the search expression is fuzzy("david", 1) 
    
  
  • the inserted value "david" is found
  
  • the inserted value "dawid" is found
  
  • the inserted value "davids" is found
  
  • the inserted value "dewid" is not found



Params:
  • query – the string to look for in the value
  • distance – the number of "uncertainties" allowed for the Levenshtein algorithm.
Returns:a predicate to apply in a GraphTraversal.

Supports fuzzy searches based on the Damerau-Levenshtein Distance, or Edit Distance algorithm
after having tokenized the data stored (case insensitive).

Example: the search expression is tokenFuzzy("david", 1) 
    
  
  • the inserted value "david" is found
  
  • the inserted value "dawid" is found
  
  • the inserted value "hello-dawid" is found
