Thanks for your reply
But metacharacter addition not working it is behaving like ,
This statement is returning fn:matches("I am learning regex","^re$") false
(expected)
But this statement is returning fn:matches("I am learning re","^re$") false
(unexpected) but I am expecting true for the same.

Subject: Re: [MarkLogic Dev General] exact match using regex
You can use anchors, as
fn:matches("I am learning regex","^re$")
7.6.2 fn:matches of https://www.w3.org/TR/xpath-functions/#flags says:
Unless the metacharacters ^ and $ are used as anchors, the string is considered
to match the pattern if any substring matches the pattern.
But if anchors are used, the anchors must match the start/end of the string (in
string mode), or the start/end of a line (in multiline mode).
Note:
This is different from the behavior of patterns in [XML Schema Part 2:
Datatypes Second Edition], where regular expressions are implicitly anchored.
