| This Analyzer uses <a class="xref" href="Lucene.Net.Analysis.Fa.PersianCharFilter.html">PersianCharFilter</a> which implies tokenizing around |
| zero-width non-joiner in addition to whitespace. Some persian-specific variant forms (such as farsi |
| yeh and keheh) are standardized. "Stemming" is accomplished via stopwords. |
