Updating Lucene Index
Hello,
I created the update index query as follows.
Query Structure:
*update-index(collection_folder, index_folder)*
But encountered a problem while implementing this.
In current Lucene indexing implementation, a document is created for each
of the xml file.
In order to retrieve a specific document from index, there should be a
unique field for a document, so that it can be retrieved using that field.
Such as File name or path. (In current implementation, only xml data is
stored in a document.)
So, I propose adding the file path to the document as a field. So that, in
the methodology that I proposed, without storing any other metadata, the
index updating can be done easily. Currently, file name, path and checksum
value are taken as metadata.
I'd like to have any feedback on this.
Thank you very much
Menaka

That field will be for the document as a whole. One unique field per
document.

Hi,
Great progress!
Would this be part of the data for each item, or is there metadata for the
document as a whole?
