Solr Schema XML Documentation

This section provides a detailed explanation of the Solr Schema XML file, which is crucial for defining the data structure and configuration for your Solr instance.

Schema XML Structure

The Schema XML file defines various components that make up a Solr schema, including:

• : This section contains all the fields defined for your schema. Each field can have attributes such as name, type, indexed, stored, etc.

• : Here, you define custom field types, which can be reused across different fields.

• : Specifies the unique key field, which is used to identify unique documents in the Solr index.

• : This section allows you to copy fields from one field to another.

Example Schema XML

Here's a basic example of a Schema XML:

<schema name="example_schema" version="1.5">
  <fields>
    <field name="id" type="string" indexed="true" stored="true"/>
    <field name="title" type="text_general" indexed="true" stored="true"/>
    <field name="content" type="text_general" indexed="true" stored="true"/>
  </fields>
  <fieldTypes>
    <fieldType name="string" class="solr.StrField" />
    <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100"/>
  </fieldTypes>
  <uniqueKey>id</uniqueKey>
  <copyFields>
    <field source="title" dest="content"/>
  </copyFields>
</schema>
