Can I index dates using the crawler?
Answer
Yes, the crawler can index dates. The crawler indexes and adds OpenGraph article:published_time and article:modified_time to a website’s schema in the Collection by default. Once this information is in your index, you can use these as boost rules, filters, or include them in a custom result interface.
You can also index additional date fields on pages by creating a field in the schema and wrapping the date field on your pages in Sajari tags. Please see our documentation for more information.
