Boosting the sxa search result by multilist field values

Question

I have a requirement where I have to boost the items in search result based on a multilist field values of the item. I have already added the target value of those multilist values to the Index using the below config.

<field fieldName="servicesprovided" returnType="stringCollection" type="Sitecore.XA.Foundation.Search.ComputedFields.ResolvedLinks,  Sitecore.XA.Foundation.Search" referenceField="services" contentField="title"/>

Below are issue i am experiencing.

• Rule where the services_sm field is case-insensitively equal to Search Box query - is NOT working as expected.
• Rule where the services_sm field is equal to Search Box query - is working only when the entered case is same as the case of field value.

Answer 1

I understood after analyzing the solr log and search over web that the boosting works case insensitively if the returnType is textCollection instead of string collection. The 'Services' field is a Tag Treelist and hence updating the return type for the same as textCollection in the config file fixed the issue.
