solr里要使用FastVectorHighlighter时须使用的配置和代码

schema.xml里配置term位置信息

 

 <field name="text" type="text_en_splitting_tight" indexed="true" stored="true" multiValued="false" [b] termVectors="true" termPositions="true"  termOffsets="true"[/b] />

如果使用了比较智能的分词，则要在solrconfig.xml里配置breakIterator

      <boundaryScanner name="breakIterator"  default="true"     
                       class="solr.highlight.BreakIteratorBoundaryScanner">
        <lst name="defaults">
          <!-- type should be one of CHARACTER, WORD(default), LINE and SENTENCE -->
          <str name="hl.bs.type">SENTENCE</str>
          <!-- language and country are used when constructing Locale object.  -->
          <!-- And the Locale object will be used when getting instance of BreakIterator -->
          <str name="hl.bs.language">en</str>
          <str name="hl.bs.country">US</str>
        </lst>
      </boundaryScanner>

最后必须在查询语句里设置useFastVectorHighlighter

query.setParam("hl.useFastVectorHighlighter", "true");
