In Sitecore, there is no dynamic field for float collection in Solr managed schema. You can add it by taking the following steps.
① Add the following packages to your Visual Studio project.
- Sitecore.ContentSearch.dll
- Sitecore.ContentSearch.SolrProvider.dll
- SolrNet.Core.dll
② Create a class inherit from the SchemaPopulateHelper, and override the GetAllFields method.
public class ExtendedSchemaPopulateHelper : SchemaPopulateHelper
{
public ExtendedSchemaPopulateHelper(SolrSchema solrSchema) : base(solrSchema)
{
}
public override IEnumerable<XElement> GetAllFields()
{
// definition of a dynamic field
var floatCollectionField = new XElement("add-dynamic-field",
new XElement("name", "*_fm"),
new XElement("type", "pfloat"),
new XElement("indexed", "true"),
new XElement("stored", "true"),
new XElement("multiValued", "true"));
/* NOTE: You can use this.CreateField instead if you use Sitecore 9.3.
var floatCollectionField = this.CreateField(
name: "*_fm",
type: "pfloat",
required: false,
indexed: true,
stored: true,
multiValued: true,
omitNorms: false,
termVectors: false,
termPositions: false,
termOffsets: false,
isDynamic: true);
*/
return base.GetAllFields().Append(floatCollectionField);
}
}
③ Create a class inherit from the PopulateFields, and override the GetHelper method.
public class ExtendedPopulateFields : PopulateFields
{
protected override ISchemaPopulateHelper GetHelper(SolrSchema schema)
{
// return a customized helper instance
return new ExtendedSchemaPopulateHelper(schema);
}
}
④ Replace the default processor to a customized one by configuration.
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:search="http://www.sitecore.net/xmlconfig/search/">
<sitecore role:require="Standalone or ContentManagement or ContentDelivery" search:require="solr">
<pipelines>
<contentSearch.PopulateSolrSchema>
<processor type="NamespaceTo.ExtendedPopulateFields, Assembly"
patch:instead="*[@type='Sitecore.ContentSearch.SolrProvider.Pipelines.PopulateSolrSchema.PopulateFields, Sitecore.ContentSearch.SolrProvider']" />
</contentSearch.PopulateSolrSchema>
</pipelines>
</sitecore>
</configuration>
⑤ Populate the Solr schema in the Control Panel.
Then, check your Solr schema in <solr>/server/solr/<core>/conf/managed-schema. You can find a definition of the dynamic field.
<dynamicField name="*_tf" type="pfloat" indexed="true" stored="true"/>
<dynamicField name="*_td" type="pdouble" indexed="true" stored="true"/>
<dynamicField name="*_pi" type="pint" indexed="true" stored="true"/>
<!-- *_fm should be added here -->
<dynamicField name="*_fm" type="pfloat" multiValued="true" indexed="true" stored="true"/>
<dynamicField name="*_t" type="text_general" indexed="true" stored="true"/>
<dynamicField name="*_i" type="pint" indexed="true" stored="true"/>
If you want to map your (Sitecore's) field to this dynamic field, you have to configure field mapping like below. (it's just a sample)
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:search="http://www.sitecore.net/xmlconfig/search/">
<sitecore role:require="Standalone or ContentManagement or ContentDelivery" search:require="solr">
<contentSearch>
<indexConfigurations>
<defaultSolrIndexConfiguration type="Sitecore.ContentSearch.SolrProvider.SolrIndexConfiguration, Sitecore.ContentSearch.SolrProvider">
<fieldMap type="Sitecore.ContentSearch.SolrProvider.SolrFieldMap, Sitecore.ContentSearch.SolrProvider">
<typeMatches hint="raw:AddTypeMatch">
<!-- Add a typeMatch -->
<typeMatch typeName="floatCollection" type="System.Collections.Generic.List`1[System.Single]" fieldNameFormat="{0}_fm" multiValued="true" settingType="Sitecore.ContentSearch.SolrProvider.SolrSearchFieldConfiguration, Sitecore.ContentSearch.SolrProvider" />
</typeMatches>
<fieldTypes hint="raw:AddFieldByFieldTypeName">
<!-- Map your field (lowercase) to floatCollection -->
<fieldType fieldTypeName="float list" returnType="floatCollection" />
</fieldTypes>
</fieldMap>
<fieldReaders type="Sitecore.ContentSearch.FieldReaders.FieldReaderMap, Sitecore.ContentSearch">
<param desc="id">defaultFieldReaderMap</param>
<mapFieldByTypeName hint="raw:AddFieldReaderByFieldTypeName">
<!-- Implement a field reader and configure for float list -->
<fieldReader fieldTypeName="float list" fieldReaderType="NamespaceTo.FloatListFieldReader, Assembly" />
</mapFieldByTypeName>
</fieldReaders>
</defaultSolrIndexConfiguration>
</indexConfigurations>
</contentSearch>
</sitecore>
</configuration>
I hope this post helps your Sitecore life.
