sorting the search words, inputted in the search word field, into one or more groups depending on their categories;

displaying, in the search expression field, the search words included in each of the groups as OR-connected nodes, while displaying connections between the groups as AND-connections; and

changing a search expression in the search expression field in response to a user'"'"'s operation that has been performed in the search word field or in the search expression field.

2. The method according to claim 1, wherein each of the OR-connections and the AND-connections are expressed by an intemodal connector.

3. The method according to claim 2, wherein the step of changing the search expression changes the search expression in response to a user'"'"'s operation on a connector in the search expression field.

4. The method according to claim 3, wherein the step of changing the search expression cancels, in response to the operation by which the connector has been moved in the search expression field, a connection relationship prior to the movement of the connector and establishes a new connection relationship after the movement.

5. The method according claim 1, further comprising the steps of:

extracting frequent words from the search results; and

displaying the extracted frequent words in a different field on the search expression creation support screen.

6. The method according to claim 5, further comprising the steps of:

determining, in response to a user'"'"'s operation by which a specific frequent word displayed in the different field has been dragged-and-dropped in the search expression field, whether or not the specific frequent word is included in an existing group;

OR-connecting a node of the specific frequent word to a node of the existing group when the specific frequent word is included in the existing group; and

AND-connecting a node of the specific frequent word to the existing group when the specific frequent word is not included in the existing group.

7. The method according to claim 6, wherein the step of AND-connecting the node of the specific frequent word to the existing group comprises AND-connecting the node of the specific frequent word to a node of an end group among those groups that are AND-connected in the search field.

8. The method according to claim 5, further comprising a step of AND-connecting, in response to a user'"'"'s operation by which a specific frequent word displayed in the different field has been dragged-and-dropped to a specific search word node in the search expression field, the specific frequent word to the specific search word node.

9. The method according to claim 1, further comprising the steps of:

adding an exclusion button to a number of individual search word nodes displayed in the search expression field; and

changing, in response to pressing of the exclusion button of a specific search word node, a connection of a corresponding search word to a NOT-connection.

10. The method according to claim 1, further comprising a step of displaying the search words in the search word field in a logical expression form when search word nodes and connectors are displayed in the search expression field.

11. The method according to claim 10, further comprising a step of applying, in response to a change in the logical expression in the search word field, the change to the search expression in the search expression field.

16. The apparatus according claim 1, wherein the search expression creation unit is further configured to display a number of extracted frequent words in a different field on the search expression creation support screen.

17. The apparatus according to claim 16, wherein the search expression creation unit is further configured to display OR-connections between a specific frequent word and a node of the existing group when the specific frequent word is included in the existing group, and AND-connections between the specific frequent word and the existing group when the specific frequent word is not included in the existing group in response to a drag-and drop operation wherein the specific frequent word displayed in the different field has been dragged-and-dropped in the search expression field.

18. The apparatus according to claim 16, wherein the search expression creation unit is further configured to display AND-connections between a specific frequent word and a specific search word node in response to a user'"'"'s operation by which the specific frequent word displayed in the different field has been dragged-and-dropped to the specific search word node in the search expression field

12. An apparatus for supporting creation of a search expression that employs a plurality of words, comprising:
