Method and apparatus for providing search service during program broadcasting

A method for providing a search service, the method comprising:

• receiving a search service request from a bidirectional broadcasting terminal in response to an input key of a user input unit;
• determining the search service request based on a rule of a search engine comprising a search providing module according to the determination of the input key action based on the rule;
• populating a first search window, the first search window displaying a representative keyword automatically being selected as the input key based on an identification of a broadcast content;
• populating a second search window, the second search window to display a search word relating to the broadcast content and the search word automatically being selected as the input key with a completion of the search word;
• and
• populating a third search window, the third search window to display a real-time hot-topic search word automatically being selected as the input key, wherein the populating the respective search window is based on the determination according the rule of the search engine.

A system, comprising:

• a search log database to store search log data collected by a search engine;
• a recommendable search word extraction module to generate a program related keyword and a modified word of the program related keyword based on the search log data;
• a real-time search word extraction module to generate a real-time hot-topic search word and a modified word of the real-time hot-topic search word based on the search log data;
• and
• a search area-providing module to provide a search area comprising a plurality of search windows in response to a search service request from a bidirectional broadcasting terminal, the plurality of search windows to display the program-related keyword and the real-time hot-topic search word automatically being displayed as an input.

A non-transitory computer-readable recording medium comprising an executable program, which when executed, performs the steps of:

• providing a search area for providing a search service on a screen of the bidirectional broadcasting terminal in response to key input of a user input unit;
• receiving a search request from a user terminal during a broadcast program;
• determining whether the search request matches with criteria of a search engine for providing a first search window to the search area, wherein the first search window is to display a representative keyword that is automatically provided as an input for searching, wherein the criteria for the matching is based on an identification of the broadcast program;
• determining whether the search request matches with the criteria for providing a second search window formed adjacent to the first search window, wherein the second search window is to display a search word that is related to the broadcast program and the search word is a completed search word automatically provided as an input;
• determining whether the search request matches with the criteria for providing a third search window formed adjacent to at least one of the first search window and the second search window, wherein the third search window is to display a real-time hot-topic search word automatically provided as an input;
• and
• providing a search window based on the determination,
• wherein each of the second search window and the third search window provides an extended pop-up window comprising a modified word of the search word displayed on the corresponding search window in response to a selection of the corresponding search window.
