基本上，我尝试在某种程度上纠正拼写，我使用查询分析器，

<analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="0" preserveOriginal="1"/>
        <filter class="solr.LengthFilterFactory" min="2" max="100" />
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt" />
        <filter class="solr.NGramFilterFactory" minGramSize="4" maxGramSize="30" />
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>

我想在NGramFilterFactory生成的标记上加上 *。如何在NGramFilterFactory生成的所有标记上加上 *？谢谢你的建议。
