The server includes a communicator which receives text information corresponding to a user voice collected at the display apparatus from the display apparatus, and a controller which extracts an utterance component from the text information and controls so that a query to search contents is generated using the extracted utterance component and transmitted to an external server which categorizes metadata of the content under each item and stores the same, in which the controller generates the query by adding a preset item to a criteria to search a content, when a number of criteria to categorize the content under an item corresponding to the extracted utterance component is less than a preset number. ## Claims ### Claim 1 A server which implements an interactive system with a display apparatus, the server comprising: a communicator configured to receive text information corresponding to a user's voice collected at the display apparatus from the display apparatus; and a controller configured to extract an utterance component from the text information, generate a query to search contents based on the extracted utterance component, and transmit the query to an external server, wherein the controller is configured to generate the query by adding a preset item to a criteria to search the contents, when a number of criteria categorizing the contents under at least one item corresponding to the extracted utterance component is less than a preset number. ### Claim 2 (depends on 1) The server of claim 1, wherein the external server categorizes metadata of the content under each of the at least one item and stores the metadata. ### Claim 3 (depends on 1) The server of claim 1, further comprising: a storage configured to store information regarding the criteria categorizing the contents under each of the at least one item, wherein the controller determines whether the number of criteria categorizing the contents under the at least one item corresponding to the extracted utterance component is less than the preset number based on the information regarding the criteria categorizing the contents. ### Claim 4 (depends on 1) The server of claim 1, wherein the controller is configured to determine the preset item to be added to the criteria to search contents based on user preference information. ### Claim 5 (depends on 1) The server of claim 1, wherein, when the contents search is not performed in response to the query generated according to the addition of the preset item to the criteria to search the contents, the controller regenerates a query to search the contents by using the extracted utterance components. ### Claim 6 (depends on 1) The server of claim 1, wherein the at least one item which has less than the preset number of the criteria categorizing the contents is at least one of a broadcasting type item and a screen quality item. ### Claim 7 (depends on 1) The server of claim 1, wherein the preset item is at least one of a broadcasting time item and a broadcasting channel item. ### Claim 8 A method for controlling a server which implements an interactive system with a display apparatus, the method comprising: receiving text information corresponding to a user's voice collected at the display apparatus; extracting an utterance component from the text information and generating a query to search a content based on the extracted utterance component; and transmitting the generated query to an external server, wherein the generating generates the query by adding a preset item to a criteria to search the contents when a number of criteria categorizing contents under at least one item corresponding to the extracted utterance component is less than a preset number. ### Claim 9 (depends on 8) The method of claim 8, wherein the external server categorizes metadata of the content under each of the at least one item and stores the metadata. ### Claim 10 (depends on 8) The server controlling method of claim 8, wherein the generating comprises determining whether the number of criteria categorizing the contents under the at least one item corresponding to the extracted utterance component is less than the preset number based on the information regarding the criteria categorizing the contents. ### Claim 11 (depends on 8) The server controlling method of claim 8, wherein the generating comprises determining the preset item to be added to the criteria to search the contents based on user preference information. ### Claim 12 (depends on 8) The server controlling method of claim 8, wherein, when the contents search is not performed in response to the query generated according to the addition of the preset item to the criteria to search contents, the generating comprises regenerating a query to search contents based on the extracted utterance components. ### Claim 13 (depends on 8) The server controlling method of claim 8, wherein the at least one item which has less than the preset number of the criteria categorizing the contents is at least one of a broadcasting type item and a screen quality item. ### Claim 14 (depends on 8) The server controlling method of claim 8, wherein the preset item is at least one of a broadcasting time item and a broadcasting channel item. ### Claim 15 A method of controlling a display apparatus based on user voices, the method comprising: receiving a user's voice at a display apparatus; transmitting the received user's voice to a first server; converting, by the first server, the received user's voice to text information, and transmitting the text information to the display device; and transmitting, by the display device, the received text information to a second server, wherein the second server extracts utterance components from the received text information and generates a query to search contents based on the extracted utterance components. ### Claim 16 (depends on 15) The method of claim 15 wherein the second server transmits the generated query to a third server which obtains search results corresponding to the user's voice, and transmits the search results to the second server. ### Claim 17 (depends on 15) The method of claim 15, wherein the second server generates the query to search the contents by adding preset items as criteria to search the contents when criteria categorizing contents under an item corresponding to the extracted utterance components are less than a predetermined number. ### Claim 18 (depends on 17) The method of claim 17, wherein the item is at least one of a broadcasting type item and a screen quality item. ### Claim 19 (depends on 18) The method of claim 18, wherein the preset number is 2.
