Hi, Even if the customer types a correct product name, how do you know that merchant A and merchant B both have registered that exact product in the same way?
Merchant A may say as product name "White Sony LCD TV XY123" and the other says "Sony XY123 LCD TV", colour=white If you're serious about price comparison service, I think you need to invest in finding what products are the same before indexing, and then tagging them with some unique normalized name. Then when after a search, you show a facet with that normalized name and first when the user has selected the correct facet, can you be 100% certain that you're comparing apples to apples. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com On 22. feb. 2011, at 07.23, Praveen Parameswaran wrote: > Hi , > @Tommaso @Jan Høydahl Thanks for the response :) > > I 've done it almost similar to what Tommaso suggested and yes it's about > 70-80% accurate. > I understand the contradiction in the search - customer find stuff without > the exact right wording (recall) at the same time as you want the query to > be precise (precision). > > In my scenario both cases are there as well, but mostly a customer would > know which product name he is searching for and he will be interested in > comparing the prices that different marchants offer.
