Multi-Facet Supports OR in Customer Portal

Prior to this feature multi-facet support in Knowledge Advanced meant that when users selected more than one sibling facet, such as two products, then the only valid answers are those that match all of the select sibling facets.  Now Customer Portal admins will be able to change this behavior to  OR between sibling facets, while continuing to AND between different taxonomies.  In other words, in the following image because both Prod1 and Prod2 are selected valid search results must have EITHER Prod1 or Prod2 assigned.  If FAQ was also selected then search results would have to be FAQs AND be assigned to one of these products.

Business Value:

If your knowledge base contains products that are similar (perhaps containing related parts or code or services) it is possible that the right answer to a question does not have all of those products assigned, in which case allowing your users to select a group of products in their filters that will be OR'ed increases their chances of finding the answer they are looking for. 

Steps to Enable

• To enable the multi-select condition feature, customer portal admins need to set the enable_multi_select attribute to true and specify the desired condition using the multi_select_condition attribute.

• Facet Widget Version: 1.8 is required

Tips And Considerations

Attribute multiSelectionCondition needs to be set to OR for the Facet Widget if you wish to take advantage of this feature
