Fail to parses SOSL with WITH USER_MODE or WITH SYSTEM_MODE

[nwcm]

Expected Behavior

Correctly parse SOSL using USER_MODE

It does seem Salesforce SOSL documentation doesn't list this... https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_sosl_syntax.htm

Actual Behavior

Warning: PMD failed to evaluate against file 'C:\Users\xx\repos\xx\force-app\main\default\classes\class.cls'. Message: ParseException: Parse exception: com.google.summit.SummitAST$ParseException: Failed to parse C:\Users\xx\repos\xx\force-app\main\default\classes\xx.cls: Syntax error at 29:13: no viable alternative at input 'WITH USER_MODE'
Syntax error at 30:6: extraneous input ']' expecting ';'

Steps to Reproduce the Problem

1. Attempt to parse the below class

public inherited sharing class soqlExample {

  public static String example(){
    String SecondarySearchList = 'test';

    List<List<SObject>> accountList = [
      FIND :SecondarySearchList
      IN NAME FIELDS
      RETURNING Account(Id, Account.Name WHERE ID = '' LIMIT 100)
      WITH USER_MODE
    ];
  }

}
