Actually, I rather agree with your colleagues, but then I'm something of a curmudgeon. More accurately, unless you _strictly_ control the input documents, you never know what you have in your index. I'd rather have docs fail indexing than be indexed with, say, typos in the field names FWIW,

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

Not that hard to setup a cron and diff job and email when the diff is not-empty. A sort-of "is that what you expected" report. But, for myself, I also prefer schema and then managed. I do not like schemaless mode, even for development. Instead, I prefer to do "dynamicField *". P.s. I am thinking

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

Shawn: Managed schema is _used_ by "schemaless", but not the same thing at all. For "schemaless" (i.e. "data driven"), you need to include the update processor chains that do the guessing for you and makes use of the managed veatures to add fields to your schema. You can also use a managed

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

I’ve never used the managed schema, so I’m probably biased, but I’ve never seen much of a point to the Schema API. I need to make changes sometimes to solrconfig.xml, in addition to schema.xml and other config files, and there’s no API for those, so my process has been like: 1. Put the entire

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

It Depends (tm). Managed Schema is way cool if you have a front end that lets you manipulate the schema via a browser or other program. There's really no other way to deal with changing the schema from a browser without allowing uploading xml files, which is a security problem. Trust me on this

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

They are different beasts, but I bet on the managed schema winning in the long run. With the bulk API, you can post a heap of fields/etc in one go, so basically, rather than pushing the schema to Zookeeper, you push it to Solr. Look at Solr 5.4 when it comes out shortly. It'll change the way

Re: Solr 5: Schema.xml vs. Managed Schema - which is advisable?

My experience is, once managed-schema is created, then schema.xml even if present is ignored. When both are present, you will get a warning in the Solr log. I have stopped using schema.xml. Actually, I use it once, start Solr and after it generates managed-schema, I export it and pretty much
