I am moving indexes from Lucene to Solr. Almost everything is working again, except a few custom indexes that have their own index configuration and had some field added to the fieldMap. Other custom indexes are working. The error I get when starting the site is:

[KeyNotFoundException: The given key was not present in the dictionary.] System.Collections.Generic.Dictionary`2.get_Item(TKey key) +13763335
Sitecore.ContentSearch.SolrProvider.SolrFieldMap.AddFieldByFieldName(XmlNode configNode) +618

The index config now:

<indexConfigurations>
    <CustomIndexConfiguration ref="contentSearch/indexConfigurations/defaultSolrIndexConfiguration">
      <fieldMap type="Sitecore.ContentSearch.SolrProvider.SolrFieldMap, Sitecore.ContentSearch.SolrProvider">
        <fieldNames hint="raw:AddFieldByFieldName">
          <field fieldName="text" returnType="string" />
          <field fieldName="webshops" returnType="string" />
          <field fieldName="attributes" returnType="string" />
        </fieldNames>
      </fieldMap>
      <documentOptions type="Sitecore.ContentSearch.SolrProvider.SolrDocumentBuilderOptions, Sitecore.ContentSearch.SolrProvider">
        ...
      </documentOptions>
    </CustomIndexConfiguration>
 </indexConfigurations>

My old Lucene config had a fieldMap like this:

<fieldNames hint="raw:AddFieldByFieldName">
    <field fieldName="text" storageType="YES" indexType="UNTOKENIZED" vectorType="NO" boost="1f" type="System.String" settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider"/>
    <field fieldName="webshops" storageType="YES" indexType="TOKENIZED" vectorType="NO" boost="1f" type="System.String" settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider"/>
    <field fieldName="attributes" storageType="YES" indexType="TOKENIZED" vectorType="NO" boost="1f" type="System.String" settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider">
</fieldNames>

I am definitely missing something (otherwise I wouldn't get an error). Buy what?

Using Sitecore 8.1-upd3, Solr 4.10.3, Autofac 4.1, ...

  • what version of sitecore and solr are you using?

  • Your code looks correct. How do you use that new Index? If you are trying to replace standard Sitecore indexes you need to keep all default fields.

  • Could you attach the full stack trace?

  • I'm not trying to replace the standard indexes. I have a few extra custom indexes next to the standard Sitecore ones. The application starts, even with some custom indexes, as long as I don't include the ones with a fieldMap in the configuration.

Reset to default

I think you may be missing type matches within your field map. Try adding this section before your <fieldNames> section

<typeMatches hint="raw:AddTypeMatch">
    <typeMatch typeName="string" type="System.String" fieldNameFormat="{0}_s" settingType="Sitecore.ContentSearch.SolrProvider.SolrSearchFieldConfiguration, Sitecore.ContentSearch.SolrProvider" />
</typeMatches>

I grabbed that from the example Sitecore.ContentSearch.Solr.DefaultIndexConfiguration.config file

Alternatively, you can try referencing the default field map like this:

<fieldMap ref="contentSearch/indexConfigurations/defaultSolrIndexConfiguration/fieldMap">

  • Your alternative (adding the "ref" to the fieldMap element) did the trick!

    This worked for me as well in working with SOLR for the first time. Elusive error. Thanks Mark!
