Date boost increases the ranking of the most recent pages. You can also adjust the decay time of the date boost to extend or shorten the period in which the documents are boosted.
For instance, a news site would benefit from the date boost with a short decay time, where the most recent topics should be ranked over the older news items.
A company site with a series of periodical reports would benefit from a date boost with an increased decay time to rank the reports higher for a longer time.
Please note that you need to specify the publishing time on the web page; otherwise, the indexing date of the web page is used.
If you want to sort results by date, you can use the settings generated by the Search Designer.
The Date boost user interface consists of Graph, Maximum multiplier, and Multiplier decay/day values.
Below the switch, you will find the search results used to monitor in real-time how the modified Date boost affects the search results.

The decay value will be subtracted from the multiplier value daily, reducing the boost over time. For example, if the Maximum multiplier property is set to 10, and the Multiplier decay/day is set to 0.75:
To modify the date boost values, follow these instructions:
