这里的suggest.txt词库默认应该是

utf-8 无BOM文档，否则solr读取有问题，

如果utf-8有BOM，那么词库第一行无法读取：

solr suggest 自定义词库和系统词库一起使用：

<!-- 可以定义多个，name查询spellchecker -->
    <lst name="spellchecker">
      <str name="name">suggestcustom</str>
      <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
      <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str>      
      <str name="field">AllContent</str>
      <float name="threshold">0.005</float>
      <str name="buildOnCommit">true</str>
      <!-- 使用自定义suggest词库词  -->  
      <str name="sourceLocation">suggest.txt</str>  
      <!-- <str name="spellcheckIndexDir">spellchecker</str> -->
    </lst>
