Abstract: In this work, we present an advanced semantic search engine dedicated to travel offers, allowing the user to create queries in the Natural Language. We started with the Polish language in focus. Search for e-commerce requires a different set of methods and algorithms than search for travel, search for corporate documents, for law documents, for medicine, etc. In travel, the complexity of data is bigger than in other domains, and the search process requires more parameters. In e-commerce, one product has 1 price, while in travel, one product (holiday package) has got tens of thousands of prices depending on time, board type, room type, number of people, children’s age, etc. Providing a search for one middle-size tour operator, we need to search within hundreds of millions documents.
