What if I add new field to schema, do I have to rebuild existing index data? In this article:
Sitecore Blogger: Boost newer documents in Sitecore 7 and Solr 4 http://www.sitecoreblogger.com/2014/09/publication-date-boosting-in-sitecore-7.html , it add a new field "_val" to schema and in the paragraph "Update Solr Schema", the author writes "you will either need to re-load this Solr Core or restart Solr so it picks up the new Schema.xml.". He never mention "rebuild existing index data". It sounds to me there's no need to "reindex" data. scott.chu，scott....@udngroup.com 2016/6/22 (週三) ----- Original Message ----- From: Alexandre Rafalovitch To: solr-user CC: Date: 2016/6/22 (週三) 14:52 Subject: Re: Do we really need to build all existing index data again afterchanging schema? [scottchu] Well, if you are changing query analyzer chain, you can get away without reindexing. But if you change index analyzer chain, then your older tokens are stored in a different ways. Even if Solr does not complain, it will not match and may lead to very obscure issues. And if you change the type radically (String to text or to integer), I am quite sure Solr will complain a lot.
