I have a core with millions of records.
I want to add a custom handler which scan the existing documents and update one
of the field (delete and add document) based on a condition (age>12 for
example).
All fields are stored so there is no problem to recreate the document from the
search result.
I prefer doing it on the Solr server side for avoiding sending millions of
documents to the client and back.
I'm thinking of writing a solr plugin which will receive a query and update
some fields on the query documents (like the delete by query handler).
Are existing solutions or better alternatives?
I couldn't find any examples of Solr plugins which update / add / delete
documents (I don't need to extend the update handler).
If someone has an example it will be great help.
Thanks in advance
