</h1>
<div class="markdown level0 summary"><p>A <a class="xref" href="Lucene.Net.Analysis.Shingle.ShingleFilter.html">ShingleFilter</a> constructs shingles (token n-grams) from a token stream.
In other words, it creates combinations of tokens as a single token.
</p>
<p>For example, the sentence &quot;please divide this sentence into shingles&quot;
might be tokenized into shingles &quot;please divide&quot;, &quot;divide this&quot;,
&quot;this sentence&quot;, &quot;sentence into&quot;, and &quot;into shingles&quot;.
</p>
<p>This filter handles position increments &gt; 1 by inserting filler tokens
(tokens with termtext &quot;_&quot;). It does not handle a position increment of 0.
