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>Alternations allow for searching alternative segments or sequences of segments, similar to the paradigmatic operator. You already have seen that you can search for both sequences of <code>der alte Mann</code> and <code>der junge Mann</code> by typing in:</p>
+
+%= korap_tut_query poliqarp => 'der [orth=alte | orth=junge] Mann'
+
+<p>However, this formulation has problems in case you want to search for alternations of sequences rather than terms. If you want to search for both sequences of <code>dem jungen Mann</code> and <code>der alte Mann</code> you can use syntagmatic alternations and groups:</p>
+
+%= korap_tut_query poliqarp => '(dem jungen | der alte) Mann'
+
+<p>The pipe symbol works the same way as with the paradigmatic alternation, but supports sequences of different length as operands. The above query for <code>der alte Mann</code> and <code>der junge Mann</code> can therefor be reformulated as:</p>

+%= korap_tut_query poliqarp => 'der (junge | alte) Mann'

 <h4>Repetition</h4>
 
 <p>Repetitions in Poliqarp are realized as in <%= korap_tut_link_to 'regular expressions', '/tutorial/regular-expressions' %>, by giving quantifieres in curly brackets.</p>

+  <p>Repetition operators like <code>{,4}</code>, <code>?</code>, and <code>*</code> make segments or groups of segments optional. In case these queries are used separated (and there are no mandatory segments in the query), you will be warned by the system that your query won't be treated as optional. Keep in mind that optionality may be somehow <i>inherited</i>, for example when you search for <code>(junge|alte)?|tote</code>, one segment of the alternation is optional, which makes the whole query optional as well.</p>
