2. Field Types
• BinaryField
• BoolField
• ByteField
• CurrencyField
• ExternalFileField
• EnumField
• LatLonType
• PointType
• TrieDateField, TrieDoubleField, TrieFloatField, TrieIntField

3. Defining Type (schema.xml)
<fieldType name="text_general" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" words="stopwords.txt" />
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>

4. Defining Fields (schema.xml)
Single Value
<field name="name" type="text_general" indexed="true" stored="true"/>
Multi Values
<field name="title" type="text_general" indexed="true" stored="true"
multiValued="true"/>
Not stored
<field name="text" type="text_general" indexed="true" stored="false"
multiValued="true"/>

5. Copying Fields (schema.xml)
• You might want to interpret some document fields in more than one way
<copyField source="cat" dest="text"/>
<copyField source="name" dest="text"/>
<copyField source="features" dest="text"/>
<copyField source="*_t" dest="text" maxChars="25000" />

6. Dynamic Fields (schema.xml)
• Dynamic fields allow Solr to index fields that you did not explicitly define in
your schema
• Dynamic field is just like a regular field except it has a name with a wildcard in it
<dynamicField name="*_i" type="int" indexed="true"
stored="true"/>
