Comment (by gorgebilly):

 The issue arises because the WordPress REST API's user search is case-
 insensitive but looks for the search term anywhere in the user's login,
 email, or display name. However, the generated users' names (from the
 script) start with "ab" followed by random characters, while the target
 user "amailer" isn't appearing due to a possible script error or a search
 parameter conflict. Here's the step-by-step

 solution:

 **Step 1: Verify the Target User Exists Correctly
 **

 {{{
 Check User Creation:
     Ensure the amailer user was created successfully using WP-CLI:
     bash
     Copy

     wp user get amailer --allow-root
 }}}


     Confirm the display_name is amailer and roles include author.

 **Step 2: Correct the Script's Username Generation**

 The script generates usernames starting with "ab", but your example
 response shows names starting with "a" (e.g., a00nBHN2n). Fix the script
 to ensure it appends the random string to "ab":

 {{{
 bash
 generate_username() {
   username="ab"  # Starts with 'ab'
   random_string=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 8 | head
 -n 1)
   username+="${random_string}"
   echo "$username"
 }

 }}}
 **Step 3: Debug the REST API Search
 **
 {{{

     Directly Access the REST Endpoint:
     Visit the URL in your browser or a tool like Postman:
     Copy

 http://10.1.190.162/index.php?rest_route=/wp/v2/users&context=view&who=authors&per_page=50&_fields=id,name&search=amailer
 }}}
         If amailer isn't listed, the user might not exist or the search is
 failing.

         If unrelated users appear, the search parameter is ignored.

 ''    Test Search via WP-CLI:
 ''

 {{{
  wp user list --role=author --search=amailer --allow-root

         If this returns amailer, the issue lies in the REST API
 configuration.
 }}}

 **Step 4: Check for Conflicts
 **
 ''    Disable Plugins:
 ''    Temporarily deactivate all plugins. If the user appears, a plugin
 (e.g., security or REST-enhancing plugins) is conflicting.

 ''    Switch to Default Theme:
 ''    Use a default theme to rule out theme-related issues.

 **Step 5: Investigate Custom Code
 **
 Check for custom filters altering user queries, such as:
 php
 Copy


 {{{
 add_filter('rest_user_query', function($args, $request) {
   // Custom logic modifying $args
   return $args;
 }, 10, 2);

 }}}

 Remove or adjust such code if it modifies the search parameter.

 **Step 6: Ensure Correct Case Sensitivity
 **
 While the REST API search is case-insensitive, ensure no custom code
 forces case sensitivity. Add a debug check in rest_api_init to log
 queries.
 Final Solution

 The most likely cause is the script generating users with unexpected
 prefixes (not "ab") or search conflicts due to plugins/themes. After
 correcting the script and ensuring no conflicts, the amailer user should
 appear when searched. If issues persist, manually check the database for
 the user’s display_name and user_login in the wp_users table.
