Erick,
Thanks for the good news, my question was still lingering from months
ago when I initially looked at an older Lucene.
Now I need a bit more specific info, since much in my architecture
rests on this ability to modify document fields dynamically. Where
can I see how IndexWriter.updateDocument works without getting into
Lucene all over again until this important issue is resolved? Is
there a sample of its usage for updating specific fields in a given
document? Is the update immediate or delayed?
Thanks, Thom

What version of Lucene are you using? The more recent ones have

Hello Lucene,
Looking at the document object it seems like each time I want to
edit its
contents I need to do the following:
1 - fetch the document
2 - dump its contents into a temp container
3 - update field values in the temp container
4 - create a new document
5 - transfer my updated field values back into the new document
6 - add document back into the index
This seems like a long process, is it really necessary?
An index structure does seem ideal for storing and searching a
large set of
symbolic strings in my app. From here I need to render these
string chars as
visible nodes on screen, this can be done with the new JavaFX API .
JavaFX has a unique binding system that would also be great to
use. Using
binding I could setup two way (inverse) binding between the fields
in a
document and the rendered screen nodes. This way when there is a
value
change in the rendered node the document field values would auto
update and
also if there is a change in the document field value the node
would auto
update.
This update senario via binding would be ideal. How can it be done?
Information about the JavaFX binding mechanism is available at
this link:

Hope this can work,
Thom
