I am trying to use schema.xml with the latest version of Solr (5.1.0). It seems that by default Solr 5.1.0 uses managed schema, but I would like to use schema.xml for a specific collection.
So I create a new collection (using solr create -c my_collection on windows and copy schema.xml from
server\solr\configsets\basic_configs\conf\schema.xml
to
server\solr\my_collection\conf\schema.xml
After that I change settings in
server\solr\my_collection\conf\solrconfig.xml
to use
<schemaFactory class="ClassicIndexSchemaFactory"/>
After doing this I get an exception when starting the server:
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: fieldType 'booleans' not found in the schema
Am I doing something terribly wrong here? Should not this kind of logic work?
UPDATE: Stractrace looks like this:

Solr schema file (schema.xml) The Solr search engine uses a schema. xml file to describe the structure of each data index. This XML files determines how Solr will build indexes from input documents, and how to perform index and query time processing. As well as describing the structure of the index, schema.
The solrconfig. xml file is located in the conf/ directory for each collection. Several well-commented example files can be found in the server/solr/configsets/ directories demonstrating best practices for many different types of installations.
The problem is that you are referencing a field type booleans that is not defined in your schema.xml file. When you create a core a file managed-schema is created in server\solr\my_collection\conf\. Rename this file to schema.xml and restart solr with ClassicIndexSchemaFactory and it will work fine.

The problem that I had here was had nothing to do with actually using the booleans field type. The problem was that the newly upgraded solrconfig.xml file has a processor for unknown fields enabled by default, which needs the booleans field type, and probably some others.
These are all defined by default in the new example schema.xml, but quite possibly not in your old schema.xml.
The solution for me was to comment out the <updateRequestProcessorChain name="add-unknown-fields-to-the-schema"> section in solrconfig.xml.
Alternatively, you can probably just replace solrconfig.xml.
