Re: Lucene Search Result with Line Numbers?

[Karl Øie]

Most indexing creates a Lucene document for each Source document. What 
would need is to create a Lucene document for each line.

String src_doc = "crash.java";
int line_number = 0;
while(reader!=EOF) {
        String line = reader.readLine();
        Document ld = new Document();
        ld.add(new Field("id", src_doc, true, true, false));
        ld.add(new Field("line", ""+line_number, true, true, false));
        ld.add(new Field("text", line.toString(), false, true, true));
        index_writer.addDocument(ld);
        line_number++;
}
This will create a small lucene document for each line, upon search you 
will find documents based on the content of the line and the line 
number as a field. The reason syntax highlighting works without 
creating a lucene document for each line is because syntax highlighting 
bases its result on groups of occurencies of text, not line numbers.

Hi, Lucene users:
  Does anyone knows how to add the Lucene search results with Line
number in original source content?
  for example:
     I have a file "Test.java" which is indexed by lucene.
     When I search inside the index, how to enhance the search result
with line number in Test.java?
  ps. the lucene sandbox has a highlighter for search result. where
can I find a line number decorator for search results?
 Thx.
 Best regards,
