When searching for airfares online, travellers are typically required to know ahead of time exactly where they�a4���a4�re going and when, and they must input those details in a specified way. Not so on Adioso, a site that uses natural language and allows for open-ended exploration.

Now in beta, Australian Adioso is �a4���Aa travel search engine for spontaneous and adventurous travellers,�a4���� in the words of its creators. The site�a4���a4�s natural-language search interface allows users to conduct searches in which both the date and the destination can be flexible, such as �a4���ASan Francisco to NYC late October,�a4���� for example, or �a4���AAustin to anywhere under $200 next week.�a4���� They can also investigate trips to anywhere in a continent or region, such as �a4���ANew York to Europe.�a4���� Adioso provides a routing engine that interconnects flights from low-cost airlines, so it also allows budget-conscious consumers to identify the lowest-cost route between any two places, domestically or internationally.

Judging by all the ongoing efforts to refine travel search, it�a4���a4�s clear there�a4���a4�s still plenty of opportunity for both generalized improvement and niche variation. One to partner with, emulate �a4���a4� or be inspired by (Related: More travel-route comparisons, now with CO2 effects �a4���a4� Trip-planning site helps find others to travel the world with �a4���a4� Travel agents bid on consumers'' dream trips �a4���a4� Event-driven travel search asks when, not where.)
