 <p>A complex segment can have multiple properties a token has to fulfill.
 For example to search for all words with the surface form <code>laufe</code> (no matter if capitalized or not) that have the lemma <code>lauf</code> (and not, for example, <code>laufen</code>, which would indicate a verb or a gerund), you can search for:</p>

 <p>The ampersand combines multiple properties with a logical AND.
 Terms of the complex segment can be negated as introduced before.</p>
