<strong>Advanced search tips</strong>
|
|
<ul class="mb-0 mt-1">
|
|
<li>Basic: type any part of a user's first name, last name, username or email (case-insensitive substring match). Example: <code>smith</code> or <code>joe@example.com</code>.</li>
|
|
<li>Wildcards: use <code>*</code> or <code>%</code> as the query to return many users (use carefully). Wildcard queries return up to 50 results; normal queries return up to 10.</li>
|
|
<li>Field-specific searches: prefix with <code>field:term</code> to restrict the search. Supported fields:
|
|
<ul class="mb-0 mt-1">
|
|
<li><code>name:</code> or <code>full_name:</code> — matches first OR last name (e.g. <code>name:smith</code>).</li>
|
|
<li><code>first:</code> or <code>first_name:</code> — matches first name.</li>
|
|
<li><code>last:</code> or <code>last_name:</code> — matches last name.</li>
|
|
<li><code>email:</code> — matches email address.</li>
|
|
<li><code>username:</code> — matches username.</li>
|
|
<li><code>id:</code> or <code>pk:</code> — match by numeric user id (e.g. <code>id:123</code>).</li>
|
|
<li><code>grade:</code> — match by grade name or grade id (e.g. <code>grade:ST3</code> or <code>grade:2</code>).</li>
|
|
</ul>
|
|
</li>
|
|
<li>Grade filter: use the grade dropdown next to the search box to narrow results by trainee grade in addition to your query.</li>
|
|
<li>To add users, click the <em>Add</em> button beside a result. If an <em>Add all results</em> button appears, it will add all currently visible results.</li>
|
|
<li>If you expect many matches, narrow your query or use a field-specific search to improve relevance and performance.</li>
