dotPeekser.SC.Solr.ManagedSchema 1.0.0

dotPeekser.SC.Solr.ManagedSchema

Provides a processor to configure the managed-schema through Sitecore.
The definition is based on the solr documentation: https://solr.apache.org/guide/8_2/schema-api.html

If a field or type already exists in solr it will be replaced. If you want to delete a specific field, the node needs to have the delete attribute with the value true in place. delete="true"

Sitecore removes all fields and types by default on every �Populate Schema� process and populates it with his own configured data. This documentation provides a flexible way to add dynamically new definitions to the managed-schema file. <br />

Caveat Example: If you configure an auto suggest handler which references a new created type you have to configure the new type in the managed-schema file even if its defined with this configuration. If you don't do it you will have a corrupt managed-schema file because solr checks the file before Sitecore populates it. Workaround: Configure it in both places to ensure the new field still exists after populate.

Base Configuration

Base node for the configuration

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <contentSearch>
      <solr.customSolrManagedSchema>
        
      </solr.customSolrManagedSchema>
    </contentSearch>
  </sitecore>
</configuration>

To apply field or type configurations, you have to define a command to reference the fields to one or multiple indexes.

To apply the configurations to a specific index, for example sitecore_master_index and sitecore_web_index you have to set the applyToIndex attribute. Each index have to be separated through a pipe character |.
If you want to apply your configuration to all indicies you can set the value to all.

<commands applyToIndex="sitecore_master_index|sitecore_web_index">
</command>

Available Command Node Attributes

applyToIndex - Which index should be modified with the configured field and types

Supported Field / Types

DynamicField, CopyField, Field, Type

Supported Field / Type Attributes

delete="true" - Definition if a field or type should be deleted

Examples (Snippets)

Dynamic Field
Add two dynamic fields *_ls_en and *_ls_de

<DynamicField>
  <name>*_ls_en</name>
  <type>lang_string</type>
  <indexed>true</indexed>
  <stored>true</stored>
</DynamicField>

<DynamicField>
  <name>*_ls_de</name>
  <type>lang_string</type>
  <indexed>true</indexed>
  <stored>true</stored>
</DynamicField>

Copy Field
Add a CopyField

<DynamicField>
  <name>*_ls_en</name>
  <type>lang_string</type>
  <indexed>true</indexed>
  <stored>true</stored>
</DynamicField>

<DynamicField>
  <name>*_ls_de</name>
  <type>lang_string</type>
  <indexed>true</indexed>
  <stored>true</stored>
</DynamicField>

Field Type
Configuration to replace text_en and text_de to have separate synonym.txt file for each language.
Ensure that all referenced filesystem files (ex. synonyms_de.txt) are placed in the correct solr folder before applying this configuration, otherwise this will have no effect! Sitecore does not show this as an error.
