Computed Field in Sitecore using Solr and Analyzers

Question

I'm trying to use an analyzer on my computed field to allow searching with spaces. Nothing I've tried works yet. Any ideas?

<contentSearch>
      <indexConfigurations>
          <defaultSolrIndexConfiguration type="Sitecore.ContentSearch.SolrProvider.SolrIndexConfiguration, Sitecore.ContentSearch.SolrProvider">
              <fieldMap type="Sitecore.ContentSearch.SolrProvider.SolrFieldMap, Sitecore.ContentSearch.SolrProvider">
                  <fieldNames hint="raw:AddFieldByFieldName">
                      <field fieldName="firstlastname" storageType="yes" indexType="tokenized" type="string">
                        <analyzer type="Sitecore.ContentSearch.SolrProvider.Analyzers.LowerCaseKeywordAnalyzer, Sitecore.ContentSearch.SolrProvider" />
                      </field>
                  </fieldNames>
              </fieldMap>
              <documentOptions type="Sitecore.ContentSearch.SolrProvider.SolrDocumentBuilderOptions, Sitecore.ContentSearch.SolrProvider">
                  <fields hint="raw:AddComputedIndexField">
                      <field fieldName="firstlastname" storageType="yes" indexType="tokenized"> Sitecore.Fields.FirstLastNameComputedField, Circle.Fields</field>
                  </fields>
              </documentOptions>
          </defaultSolrIndexConfiguration>
      </indexConfigurations>
  </contentSearch>

Answer 1

To have included spaces into your index at population you need to specify indexType="UNTOKENIZED", and then at the indexing the spaces are not removed.

If you want to use analyser, your current analyser removes spaces and converts them into lowercase. Example: Input: "I just LOVE my Phone!" Output: "i", "just", "love", "my", "phone"

Check other analyzer if you want spaces and use untokenized for computed index field:

<field fieldName="firstlastname" storageType="yes" indexType="UNTOKENIZED"> Sitecore.Fields.FirstLastNameComputedField, Circle.Fields</field>
                  </fields>

Answer 2

I'm not sure when it changed but in Sitecore 10.x you now need to change the returnType parameter which is used for whether the field gets tokenized or not. For example string does not get tokenized but text does.

<field fieldName="firstlastname" returnType="string"> Sitecore.Fields.FirstLastNameComputedField, Circle.Fields</field>
                  </fields>
