Re: database search using Lucene

Hi,

I am getting compile time error symbol not found on line
doc.add(Field.Text("contents", new FileReader(f)));
doc.add(Field.Keyword("filename", f.getCanonicalPath()));
of method indexFile(IndexWriter writer, File f)

when i look into class Field i didn't found any thing about Text and
Keyword symbol.

what i have to do to resolve above compile time error...
