This feature was earlier called Filter Precision.
# **What is Facet Precision**
Facets enable your customers to drill-down and refine the product recall set based on certain attributes. Relevant facets make product discovery easy and intuitive.
In some instances, you may come across irrelevant facets and facet values being displayed in the search results. facets and facet values may become noisy when your product recall is noisy. The product recall can be noisy if you have noisy fields marked searchable. Irrelevant facets may confuse and frustrate users, leading to a poor search experience.
Precision mode available for search can sometimes remove relevant (or related) products that customers might want in the recall set.
**Facet Precision** feature targets and removes facet noise in search results. It helps clean up the irrelevant facet coming from the products buried in the search results.
For instance, your customer searches for the query “_red throw pillows_”.
Without Facet Precision applied, the product results show the following facets on page 1:
**Relevant facets**: _Color_, _Pillow Cases, Sheet Sets, Outdoor Pillows_
**Irrelevant facets**: _Vase, Throws, Candles_
When you apply Facet Precision, these irrelevant facets are dropped automatically. This allows your customer to narrow down the search results using the most relevant attributes/categories.
**Note**: Facets and Filters are synonymous in the context of Bloomreach Discovery.
No change in the product recall set
Facet Precision doesn’t change the product recall set. It just eliminates the facet noise.
# **Why is this feature valuable for your Business**
**Less manual work, more scalability:** Facet Precision reduces the need to create facet rules as it cleans up irrelevant facets automatically. This helps improve your site’s search experience at scale.
**Improved relevance that can lead to more revenue:** With a contextual search experience, customers can easily find the products they're looking for. This leads to faster conversions and more revenue for your business.
**Better customer experience**: Relevant facets make product discovery effortless for your customers. With precise facets, customers can easily refine the results based on meaningful attributes. This results in improved product findability and faster conversions.
# **How does this feature work**
When you enable Facet Precision, it displays the most relevant facets and facet values that match your customer’s search query.
The relevant facets and facet values are determined based on the products in the dominant categories of that query. Dominant categories are determined based on the top 50 products in the recall set. We can customize this limit for you, but the default value is 50.
For example, for the query "_dress_", the top 50 products might belong to "evening dress", "maxi dress", "cocktail dress" categories. The 78th product might be a pair of dress shoes that belong to the "men shoes", and "women shoes" categories.
In this case, "men shoes" and "women shoes" will not be a part of the dominant category set (since products from these categories don't appear in the top 50); "evening dress", "maxi dress", "cocktail dress" will be in our dominant categories list. Hence, the facets and facet values will be generated based on the products in the recall set which do exist in these dominant categories. The API response will not return any facets or facet values related to "dress shoes".
