We’re working on large eCommerce site which is based on ASP.NET MVC3(C#). We are planning to implement Solr for better search result.
There is a one feature named “Most Popular Product” in site.As named suggest,It displays most popular product on site based on how many times that particular product viewed by customer.
On Product detail page or product listing page,we distinguish it by putting an unique(most popular icon) icon which indicates most popular product.
Now our problem is that,How can we update flag or status that product identify as most popular in solr index? or How can we relates this features with solr?
Note: It is very costly to update whole solr index for fulfill this functionality.
Use ExternalFileField to store popularity data for products (it’s available in 3.6 too). This lets you update that field without the need to reindex anything.
