<p>All analyzers support setting custom <code class="literal">stopwords</code> either internally in

<p>The <code class="literal">stem_exclusion</code> parameter allows you to specify an array
of lowercase words that should not be stemmed. Internally, this
functionality is implemented by adding the
<a class="xref" href="analysis-keyword-marker-tokenfilter.html" title="Keyword Marker Token Filter"><code class="literal">keyword_marker</code> token filter</a>
with the <code class="literal">keywords</code> set to the value of the <code class="literal">stem_exclusion</code> parameter.</p>
<p>The following analyzers support setting custom <code class="literal">stem_exclusion</code> list:
<code class="literal">arabic</code>, <code class="literal">armenian</code>, <code class="literal">basque</code>, <code class="literal">catalan</code>, <code class="literal">bulgarian</code>, <code class="literal">catalan</code>,
