I need build a shop comparison site like this one http://www.moneysavingexpert.com/megashopbot. I need the results to be sorted by store, brand, price, in a list or a grid, narrow down the price range, and find sales items. The search engine is to access other sites that I will enter their url and or get the xml feed from those sites; Meaning that I am going to be searching more than one site at once i.e search about pricecomparison sites. Only products to be displayed. I know the google basic search can do that I need my site to bring out results that are ONLY RESTRICTED TO THE URLS that I have put in it for it to search. I think the search engine is to have a database program like sql or oracle that will store the information before the user make a query. Linus they say have some nice database applications*********** You understand? Does it make any sense. Programmer should find out if you can use yahoo's API to achieve this same task or http://shopping.yahoo.com/syndication/;_ylt=AhoLmvL55Kn_Zj.F4uUO6NgEgFoB OR GOOGLE http://code.google.com/apis/ajaxsearch/ I will provide content. I will make payment with scriptlane. Fast payment. More projects coming.
