The Quote Line Editor's Search Filter allows you to filter a Quote's Products, Assets or Subscriptions based on their field values - for instance, you could search for all Products where the Product Name field contains "Monitor". Salesforce CPQ allows you to search Product Code, Product Name, Product Family and Product Description by default, but users can add standard or custom fields to any search filter.
Users should create a new Search Filter object and set its fields to target to the object/field they want to search. For instance, you could search the values of the Industry field on the Quote object. An "Industry" search filter will then appear in the Quote Line Editor.
Search Filter Advanced Information Definitions
Search Filter Advanced Information fields can create dynamic Search Filters. For example, a sales rep may want to filter Products based on the Country they're quoting to.
