查找搜索词的偏移量lucene.net，C＃ [英] Finding offsets of a search term in lucene.net,c#

问题描述

我

如何能获得该在Lucene.net?I要搜索使用FastVector荧光笔突出显示文本？

注意我的标记偏移：我已经有一个已使用标准分析索引，现在我有兴趣获取特定符号

的偏移所有令牌的偏移量

  testhighlighter TST =新testhighlighter（）; 
 
 
 Lucene.Net.Analysis.Token净额= tokenstream.Next（）; 
 INT startoffset = net.StartOffset（）; 
 INT endoffset = net.EndOffset（）; 
  

解决方案

您可以尝试TermVectorMapper获取方面的立场和偏移

的 http://permalink.gmane.org/gmane.comp.jakarta.lucene.net.user/3203

 类TVM：TermVectorMapper 
 {
公共覆盖无效SetExpectations（串场，诠释numTerms，布尔storeOffsets，布尔storePositions）
 {
} 
 
公共覆盖无效地图（串词，INT频率，TermVectorOffsetInfo []偏移，INT []位置）
 {
} 
} 
 
 TVM TVM =新TVM（ ）; 
 reader.GetTermFreqVector（docID的，现场，TVM）; 
  

How could I get offsets for the tokens that has to be searched in Lucene.net?I am using FastVector Highlighter for highlighting a text?

Note:I have already got the offsets of all the token that has been indexed using Standard Analyzer and now I would be interested in getting the offsets of the particular token?

 testhighlighter tst = new testhighlighter();


           Lucene.Net.Analysis.Token net = tokenstream.Next();                        
                    int startoffset = net.StartOffset();
                    int endoffset = net.EndOffset();

解决方案

You can try TermVectorMapper to get positions and offsets of terms.

http://permalink.gmane.org/gmane.comp.jakarta.lucene.net.user/3203

class TVM: TermVectorMapper
{
public override void SetExpectations(string field, int numTerms, bool storeOffsets, bool storePositions)
    {
    }

    public override void Map(string term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions)
    {
    }
}

TVM tvm = new TVM();
reader.GetTermFreqVector(docID, field, tvm);
