You can create a link to a page using the Product Listing or Full Product Listing control. After the link is created, the page will load with a filter applied. In order to set the filter, follow the guidelines described below.
Append this without spaces/line feeds to the page URL:
#filter=
{"Facet"%3A{"Name"%3A"Events","Value"%3A"WEB_FACET_2"},
"SubFacet"%3A{"Name"%3A"Sessions","Value"%3A"SESSIONS"},
"Category"%3Anull,
"SubCategory"%3Anull}
&searchTerm=
&searchItemNameTerm=
&searchDescriptionTerm=
&productClass=
Facet, SubFacet, Category, and SubCategory should either read as "Category"%3Anull or "Category"%3A{"Name"%3A"Books","Value"%3A"BOOK"}
The search terms and product class should be empty with no spaces to not have a search, if they do have a search it should read as
… &searchTerm=medic&searchItemNameTerm= …
The %3A is the URL encoding for colon (:)
