Re: [Dotlucene-developer] dotlucene and sql db

[Ivan V. Ai <ved...@gm...>]

I think you can't...
... but there is remote possibility I might be wrong, since I haven't
fully explored the entire source code yet. ;)

anyway,
What you might need to do is find-delete (preferably by PK Keyword
identifier) the document that has changed and then Add new document
with new data. I used the procedure described in:
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=luc...@ja...&msgNo=6300

In addition, you also might wish to use RAMDirecotry for updates and
then "flush-combine" it on disk (or any other appropriate permanent
storage) index using:
  AddIndexes(new Directory[] {oldIndexStorage, updateIndexStorage})
method of new IndexWritter.

Regards,
Ivan
