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.
