      <h3>How to Use Search Operators</h3>
      <ul>
        <li><strong>Simple keyword</strong> — type any word to find entries that contain it.<br>
            <em>Example:</em> <code>faith</code></li>
        <li><strong>Phrase search</strong> — put quotes around a phrase to match it exactly.<br>
            <em>Example:</em> <code>"Jehovah is my shepherd"</code></li>
        <li><strong>OR search</strong> — use <code>OR</code> (uppercase) to match any of several terms.<br>
            <em>Example:</em> <code>love OR kindness</code></li>
        <li><strong>Exclude terms</strong> — use a minus sign to remove results containing a word.<br>
            <em>Example:</em> <code>hope -future</code></li>
        <li><strong>Wildcard search</strong> — use <code>*</code> to replace part of a word.<br>
            <em>Example:</em> <code>lov*</code> finds <code>love</code>, <code>loved</code>, <code>loving</code></li>
        <li><strong>Scripture search</strong> — type a Bible book or abbreviation to find entries that reference it.<br>
            <em>Example:</em> <code>John 3:16</code></li>
      </ul>
      <p><strong>Tip:</strong> Combine operators:<br>
         <em>Example:</em> <code>"good shepherd" OR "faithful servant" -parable</code></p>
