# Date filter

You may choose to filter your search results based on the publication date of the document. SureChEMBL allows you to specify a range of dates for this filter.

Note: *See* [*Solr query field names and examples*](/surechembl/text-search/solr-query-field-names-and-examples.md) *for an extended explanation of writing date filtering using Solr.*

Note2: *The use of truncation is not supported within date filtering.*
