To exclude a facet range field in Solr, you can use the "facet.field" parameter in the Solr query and set the value to the field you want to exclude. By omitting the desired facet range field from the facet field list, you can effectively exclude it from the facet results. This allows you to customize the facets that are returned in the search results based on your requirements. By excluding certain facet range fields, you can focus on displaying only the facets that are most relevant or important for your search application.

How to filter out facet range field in Solr?
To filter out facet range fields in Solr, you can use the "fq" parameter in the Solr query.
The "fq" parameter allows you to apply a filter query to the search results, which will only include documents that match the filter query.
For example, if you have a facet range field called "price" and you want to filter out all documents where the price is greater than 100, you can add the following filter query to your Solr query:
&q=:&fq={!frange l=0 u=100}price
This query will only return documents where the price range is between 0 and 100. You can adjust the range values in the filter query as needed to filter out the facet range field according to your specific requirements.
How to prevent a facet range field from appearing in facet counts in Solr?
To prevent a facet range field from appearing in facet counts in Solr, you can use the facet.mincount parameter in your Solr query.
For example, if you have a facet range field called price and you want to exclude it from appearing in facet counts, you can set the facet.mincount parameter to a value of 2 or higher. This will ensure that only facet values with a count of 2 or more will be included in the facet counts, effectively excluding the price facet range field from the results.
Here is an example Solr query that excludes the price facet range field from facet counts:
1
|
q=*:*&facet=true&facet.field=category&facet.mincount=2
|
In this query, the facet.mincount parameter is set to 2, meaning that only categories with a count of 2 or more will appear in the facet counts. The price facet range field will not appear in the facet counts unless it meets the minimum count threshold.
What is the purpose of excluding a facet range field in Solr?
Excluding a facet range field in Solr means that the values of that field will not be used for faceting or filtering in search results. This can be done to reduce the amount of data being processed and improve performance if the facet range field is not essential for the search functionality. It can also be used to simplify the user interface by not displaying unnecessary facet options.
What is the method for excluding facet range field values in Solr?
To exclude facet range field values in Solr, you can use the "ex" parameter in the facet query. Here's an example of how to exclude facet range field values in Solr:
1
|
http://localhost:8983/solr/<collection>/select?q=*:*&facet=true&facet.range=price&facet.range.start=0&facet.range.end=100&facet.range.gap=10&fq={!tag=price,ex=-20}[price:0 TO 100]
|
In this example, we are excluding the range of values from -20 to 100 for the "price" facet range field. The "{!tag=price,ex=-20}" part tells Solr to exclude values from -20 to 100 from the facet range field "price".
You can adjust the range values and field name according to your specific requirements.
