Method and system for searching for and/or purchasing products or services

A system for searching for a product or service and presenting the results in a calendar type view;

• wherein the search is instigated in a request which includes a plurality of parameters, such as a city pair and/or a date, and one or more upsell criteria;
• the system comprising:
• a search engine for determining via a computer search, results which meet at least one parameter and one or more upsell criteria to thereby determine a flight domain;
• wherein the search engine progressively searches the flight domain at a plurality of abstraction levels to produce refined results and further limits the number of results in the flight domain based on the at least one parameter, one or more upsell criteria and a first one of a plurality of abstraction levels to obtain refined results having lowest prices;
• and
• a display for presenting the refined results in a view such as a calendar matrix view.

A computer program comprising instructions for carrying out the steps of a method of searching for a product or service and presenting the results in a calendar type view;

• wherein the search is instigated in a request which includes a plurality of parameters, such as a city pair and/or a date, and one or more upsell criteria;
• the method comprising the steps of:
• determining via a computer search, results which meet at least one parameter and one or more upsell criteria to thereby determine a flight domain;
• progressively determining the flight domain via a computer to produce refined results;
• limiting the number of results in the flight domain based on the at least one parameter, one or more upsell criteria and first one of a plurality of abstraction levels to thereby obtain the refined results, which refined results have lowest prices;
• and
• presenting the refined results in a view such as a calendar matrix view, when said computer program is executed on a computer system.
