Hello and thank you for your answers. I'll try to explain my problem a little better:
The goal is to manage ACLs via Solr without reindex the documents at each change of permission. I have hundreds of thousands of documents, users and groups and permissions (allow / denied) or each of these groups of these users.
I read a lot of things about this and it seems that the binary compraison is the best solution ... but I may be wrong :/
To do this I saw a plugin here: https://issues.apache.org/jira/browse/SOLR-1913 with an example of this: https://docs.google.com/document/d/10HuqHkYjaEm6Q2ZrRCI0QQMLbbqtRv_NXDHcTjfCRfU/edit? fold = 1
Unfortunately I have not managed to successfully install the plugin although I followed the steps it seems ...
At the moment I left on a solution that is to use dynamic boolean fields but I'm afraid to face performance issues on important volumetries in terms of documents and fees.
I hope I have been more specific, I await your ideas because I'm not having chosen the right solution ... small clarification: I discovered solr only a few months ago: s
Thanks, Christopher
