Updating an index

[ph...@free.fr]

Hello,

I have [mistakenly] created a SOLR index in which the document IDs contain URIs such as file:///Z:/1933/01/1933_01.png .

In a single SOLR update command, how can I:

- copy the contents of each document's id field to a new field called 'url', after replacing 'Z:' by 'Y:'

- make SOLR generate a new random Id for each document

Many thanks.

Philippe

I echo that. Atomic update is merely a decoration over the same
delete/insert pattern, where Solr processor inplace retrieves all the
stored fields of the the document, updates the field, then checks _version_
field prior to update and if it was correct, deletes, then insert new
version of the document.

No way that I know of, re-indexing is in order.

Solr does not "update in place", you have to re-add the document. Well,
AtomicUpdates work but iff all fields are stored. And it still wouldn't
be a single Solr command.

Best,
Erick
