Filters are built on top of product or item attributes. These attributes collectively define an individual item in the search catalog. When search results are composed for a query, based on these attributes or fields, a summary(aggregation) of field values and their count(occurrence) are computed. These are shown to user so that they can narrow down search results to some particular section of following user expected criteria.
More on Filters:
- Filters are parent categories, applied upon which unmatching pages or content will be eliminated from results immediately.
- Filters never change between searches, unlike facets change based on what are search results actually.
- Filters can be applied before entering a search query and after search results are shown.
