In Solr, you can search for more than one facet by using the "fq" (Filter Query) parameter. This parameter allows you to apply multiple filters to your search query. For example, if you want to search for products that belong to both the "Electronics" and "Laptops" categories, you can use the following query:
q=:&fq=category:Electronics&fq=category:Laptops
This query will return only products that belong to both the "Electronics" and "Laptops" categories. You can add as many filters as you need by separating them with an ampersand (&) in the "fq" parameter. This allows you to search for products that match multiple facets at the same time.

How to customize facets in Solr?
To customize facets in Solr, you can use the facet.field parameter to specify which field you want to facet on. You can also use the facet.limit parameter to control the number of facet values returned for each facet field. In addition, you can use the facet.sort parameter to specify how you want the facet values to be sorted (e.g. by count or by index order). You can also use the facet.mincount parameter to specify the minimum count that a facet value must have in order to be included in the results. Finally, you can use the facet.prefix parameter to filter the results to only include facet values that start with a specific prefix.
These are just some of the parameters that you can use to customize facets in Solr. You can find more information about customizing facets in the Solr documentation.
What is faceted filtering in Solr?
Faceted filtering in Solr is a feature that allows users to filter search results based on certain criteria or facets. These facets are predefined categories or attributes of the indexed data, such as product categories, brands, prices, sizes, etc. When a user performs a search query in Solr, the search results can be grouped and filtered based on these facets, allowing users to easily find relevant information.
Faceted filtering in Solr is often used in e-commerce websites and other applications where users need to quickly narrow down search results based on specific criteria. It helps in improving user experience by enabling users to refine their search results and find exactly what they are looking for.
How to perform faceted search in Solr?
Faceted search is a way of displaying search results that groups items into categories and provides users with an interface to filter and refine their search results. In Solr, faceted search can be implemented using the facets component.
Here is a step-by-step guide on how to perform faceted search in Solr:
- Configure your Solr schema to include the fields that you want to facet on. You can define these fields as "facet fields" in your schema.xml file.
- Enable faceted search in your query by including the "facet=true" parameter in your URL when making a search request to Solr.
- Specify the fields that you want to facet on by using the "facet.field" parameter in your query URL. For example, if you want to facet on the "category" and "price" fields, you would add "facet.field=category&facet.field=price" to your query URL.
- Make a search request to Solr, and Solr will return the search results along with the faceted search results based on the specified facet fields.
- You can render the faceted search results in your search interface by displaying the facet categories and their respective counts. Users can then click on the facet categories to filter the search results based on their selections.
By following these steps, you can implement faceted search in Solr to provide users with a more interactive and intuitive search experience.
