Usage examples

The following checks if a sorted collection contains a value:

RETURN apoc.coll.containsSorted([1,4,5], 4) AS output;

Table 1. Results
Output
TRUE

This function will not work on unsorted collections, as shown in the example below:

If we want to find a value in an unsorted collection, see apoc.coll.contains.
