For users who have defined facets, after running a search test, a list of facets displays, accompanied by facet selections on the bottom of the inputs portion of the Search Testing screen. To see only the products and SKUs in a given facet selection, you run a secondary test with that selection checked. The default setting lets you specify one facet selection per test; however, you can configure Merchandising to permit multiple selections.
If users create tests to troubleshoot their web site’s behavior, whether you want to use single or multiple selection depends largely on how the site implements facets. The single-select option replicates sites that use faceting:
As a navigational tool that permits users to click one facet before displaying the products and SKUs it contains. For example, clicking the Women faceting selection displays all clothes for females.
As a searching tool, so that when users search for a given term, the results are facet selections. Clicking a facet selection displays the products and SKUs it contains. For example, searching for “shoes” returns two selections: Men and Women. Clicking Men displays individual shoes suited for men.
The multi-select option represents sites with inherited and/or nested facets that employ faceting:
As a navigation tool by permitting users to click successive selections to filter out certain results. For example, clicking the Women selection causes the selections Clothes, Shoes and Accessories to display. In turn, clicking Shoes returns another group of selections, some representing prices (up to $100, $100-200, $200- 300) others representing sizes (5, 5.5, 6. 6.5), and a third for sale items. These selections hold products.
As a searching tool where users can use faceting selections as search criteria. For example, a user might define criteria to find all shoes from $100-200 in size 7 that include the search text “high heels.”
When Merchandising is configured to use multi-select, you are able to specify multiple selections for a given facet (up to $100 and $100-200) as well as specify selections derived from different facets ($100200 and size 7).
To change your setting from single-select to multi-select, find the SearchTestingQueryFormHandler in the /atg/commerce/search/testing directory and change the facetInputMode property from single to multiple. If the property is empty, multiple is used.
