              Search occurs on each character you type (3 character minimum for search

            </p>
            <p>
              <b>The index:</b> Search utilizes the index which automatically gets updated
              on the configured interval (default: 5 minutes). Searching when the program
              has just started may result in incomplete results.
            </p>
            <p>
              <b>Filter by type:</b> You can have multiple type filters by adding
              <code>type:condition</code> followed by search terms.
            </p>
            <p>
              <b>Multiple Search terms:</b> Additional terms separated by <code>|</code>,
              for example <code>"test|not"</code> searches for both terms independently.
            </p>
            <p>
              <b>File size:</b> Searching files by size may have significantly longer
              search times.
