Use advanced similarity rules to view similar case suggestions
Quickly support your customers by viewing similar cases suggestions in the Customer Service Hub. As an administrator, you can now configure criteria using advanced similarity rules, so that agents can view cases similar to their current case and resolve customer issues in first contact and within minimal time frame. This helps to reduce operational cost and in turn increase customer satisfaction.
If an agent is working on a support case, they can view similar cases in the Related section of the current case, and resolve their case quickly. With the help of Relevance search, they can use keywords or key phrases in a service case to quickly find related cases and use them to resolve customer issues.
Similar case suggestion scenario
Gilda is resolving an issue where a customer isn't able to book a travel package on the portal. To assist the customer quickly, Gilda seeks guidance by looking for similar cases in the Similar cases tab in the Related section of the current case.
Based on configured data input, the Relevance search mechanism filters the cases using key phrases and suggests a list of cases. Gilda selects a relevant case and glances through the details. Gilda is able to resolve the customer issue with this suggested case and can also link the case to the current case for future reference.

Understand how relevance search impacts search results
See the below table to understand how search results are impacted when Relevance search is enabled or disabled.
| Relevance search disabled | Relevance search enabled |
|---|---|
| Based on the similarity rules, search is performed across primary field of an entity. | Based on the attributes configured in similarity rules, search is performed on entity attributes configured for relevance search. |
| For example, if similarity rules are configured on Title and Category, comma-separated attribute text is passed to look for a match in the Case title of case entity. | For example, if similarity rules are configured on Title and Category, and Relevance search is enabled on Description, the search is performed for Title and Category in the Description field of case entity. |
