Hi We're looking to migrate some custome Lucene queryparser plugins and custom request handlers that we wrote with Solr 4.3 to the latest version of Solr. While we're at it, we would also like to move to Solr Cloud. Should we expect these plugins/request handlers to be compatible with the Solr Cloud architecture i.e hopefully minimal changes to get them to work? Are there any pitfalls or things to look out for ? Just wanted to do some risk assessment before we start going down this path.
FWIW, they allow for custom query syntax to be used which invoke custom functionality (custom filters and collectors). Thanks in advance for any feedback and pointers to appropriate content. Regards Chetan
