- Keep facets to a maximum of 40. This is not a hard limit. However, performance degradation becomes noticeable when the maximum is reached.
- Facet values should not exceed 1,000.
- Each facet value’s name should be under 200 characters.
- Only include facets when they are necessary.
- When making a request to the Item Search API, omitting
include=facetsfrom the request URL ensures that the facets are not generated and returned. This improves performance. - If you do need facets, but you know you can exclude specific ones, then using
facet.excludein your request URL can remove that facet from the results.
