I am using lucene to index rows in a spreadsheet , each row is a
Document, and the document indexes 10 fields from the row plus the row
number used to relate thethe Document to the row number
So when someone modifies one of the 10 fields I am interested in a row I
have to update the document with the new data
writer = new IndexWriter(directory, analyzer);
Document document = createDocument(row);
writer.updateDocument(new Term(ROW_NUMBER, "" + row), document);
writer.optimize();
writer.close();
Because I can't retrieve the existing Document for a row from a writer I
recreate the document when one of the values has changed, but this means
I have to go off and get all the values again even though I am only
changing one. is there a better way to do this, I thought
that I could retrive the document using an IndexReader and then modify
it using removeField(),AddField() but there is extra overhead in doing
in having to create a reader to get the document - so which would be best.
thanks Paul
