Hi Mark Yes, it is something we implemented also. We just try various subsets of the search terms when there are zero results. To increase performance for all these searches we return only the first three results and no facets so we can simply display the result counts for the various subsets of the original search terms. We only do this if the first search had zero results and then a double metaphone search (which is how we handle misspelled terms) also returned nothing. We also apply various heuristics to the alternative searches being performed like no one word searches if the original search had many words etc
Thanks Robi -----Original Message----- From: Mark [mailto:[email protected]] Sent: Wednesday, July 31, 2013 10:35 AM To: [email protected] Subject: Alternative searches Can someone explain how one would go about providing alternative searches for a query... similar to Amazon. For example say I search for "Red Dump Truck" - 0 results for "Red Dump Truck" - 500 results for " Red Truck" - 350 results for "Dump Truck" Does this require multiple searches? Thanks
