Hi,
The settings are explained here:
www.hikashop.com/support/documentation/1...-filter-listing.html
The "apply on" setting allows you to select the columns on which the search will be done.
So normally, you want to select "product name", maybe "product description", maybe "product code", etc.
The "Search Processing" setting allows you to change the behavior of the search:
"Every words" will distinctly search each word typed (but they both have to appear somewhere), "complete expression" will search for the whole expression, "any word" will search for each word with or without the others. Finally the search operators features allow our customers to use quotes for a complete expression search (like "red balloon"), plus for a every word search (red+balloon) and spaces for an any word search (red balloon)
Regarding the sorting of the results, this is dictacted by the "ordering column" and "ordering direction" settings of the products listing used for the search results display.
There is no mechanism to count the amount of matches for each product and then sort the results based on that.
While I understand that it would be great, it's quite complex to add and will also slow down the search quite a lot. So I don't see how we could do it without rewritting a big part of the filter system to have a caching mechanism on the searches. It would be weeks of development.
