| multiple tokens for each consumed token</p> |
| <p> |
| Note: This filter is aware of the <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Analysis.TokenAttributes.KeywordAttribute.html">KeywordAttribute</a>. To prevent |
| certain terms from being passed to the stemmer |
| <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Analysis.TokenAttributes.KeywordAttribute.html#Lucene_Net_Analysis_TokenAttributes_KeywordAttribute_IsKeyword">IsKeyword</a> should be set to <code>true</code> |
