No-result Checklist

Step 1: Determine impact

• How often does the search term occur?
• Is the term commercially relevant?
• Is this a one-time error or structural pattern?

Step 2: check spelling

• Does the search question include a typo?
• Does fault tolerance work for this variant?
• Can the correct term be found?

Step 3: check synonyms

• Does the customer use a different name than the catalogue?
• Is it a local or industry-specific term?
• Should an explicit synonym be added?

Step 4: check product data

• Does the product actually exist in the feed or index?
• Are relevant attributes filled?
• Is the product in the right category?

Step 5: check filters and rules

• Does a set filter exclude all products?
• Does a merchandising rule block a result?
• Is the product available for this market or store?

Step 6: rate assortment

• Do the customer expect a product that is not sold?
• Can an appropriate alternative be shown?
• Is the demand large enough for assortment research?

Step 7: Measure after adjustment

• Has the no-result disappeared?
• Are results actually clicked?
• Does the search term eventually lead to conversion?
