# Facet filters & dynamic faceting

| Feature                                    | Description                                                                                                                                                                                                                                                                                                                                                                                                             |

| **Facet filters on any product attribute** | Faceted filters can be built using any product attribute (date, number or text). Brand, category and price are default. Allow users to select and deselect facets. Applying a facet will narrow the search results and new facet values will be re-calculated based on the filtered results. All faceting options with a value >0 (i.e. the count of products that contain that filterable attribute) will be returned. |
| **Dynamic faceted filters**                | The engine can decide what facets are relevant for the current search result and strip away any irrelevant facets. This is particulary relevant for stores with many facets and a lot of broad searches.                                                                                                                                                                                                                |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fact-finder.com/infinity/spec-sheet/site-search/facet-filters-dynamic-faceting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
