<p>All analyzers support setting custom <code class="literal">stopwords</code> either internally in
the config, or by using an external stopwords file by setting
<code class="literal">stopwords_path</code>. Check <a class="xref" href="analysis-stop-analyzer.html" title="Stop analyzer">Stop Analyzer</a> for

<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">bengali</code>, <code class="literal">bulgarian</code>, <code class="literal">catalan</code>, <code class="literal">czech</code>,
