⎊dynamicField.md

The schema.xml in the example application that ships with solr 4.0.0-BETA defines a couple of dynamic fields we can use.

<dynamicField name="*_txt" type="text_general" indexed="true"  stored="true" multiValued="true"/>

*_txt fileds are repeatable of type text_general

And for facets, we use can use

<dynamicField name="*_ss" type="string"  indexed="true"  stored="true" multiValued="true"/>

the *_ss dynamic field stores repeatable strings

<!-- The StrField type is not analyzed, but indexed/stored verbatim. -->
<fieldType name="string" class="solr.StrField" sortMissingLast="true" />

Also, everything gets copied into a field named text of type text_general, for keyword search across all fields:

<!-- catchall field, containing all other searchable text fields (implemented
        via copyField further on in this schema  -->
<field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>

The text_general type used by the *_txt and text fields is defined as

    <!-- A general text field that has reasonable, generic
         cross-language defaults: it tokenizes with StandardTokenizer,
	 removes stop words from case-insensitive "stopwords.txt"
	 (empty by default), and down cases.  At query time only, it
	 also applies synonyms. -->

also edit solr/example/solr/collection1/conf/solrconfig.xml or otherwise set facet.* parameters; and the search results template solr/example/solr/collection1/conf/velocity/richtext-doc.vm needs to be edited to show your fields.
