<p>PURPOSE: A touch based search system is provided to increase accessibility to information, by displaying searchable words, whose top and bottom concept is established in tree structure, in the sequence of high relation by up and down/left and right recurring method. CONSTITUTION: A searchable database (112) stores searchable words, and stores degree of relation among searchable words in the same level on the tree structure. A searchable word selection part (114) lists and displays the searchable words in the same level on the tree structure by up and down/left and right recurring method on a display part of a user terminal capable of touch input. If a touch signal selecting a specific searchable word is inputted, the searchable word selection part sets the selected searchable word as search word, and transmits the selected searchable word to a search engine (140). The search engine searches online information including the search word in an online information database (120), and outputs the searched online information to the screen.
