Abstract

Provided is a document search apparatus including a reception unit that receives plural search words in a hierarchical relationship, and a setting unit that sets a first content among plural contents in a hierarchical relationship included in structured document data, as a search range of a first search word received by the reception unit, and sets a second content at a same hierarchical level as a hierarchical level of the first content or a hierarchical level lower than a hierarchical level of the first content, as a search range of a second search word at a hierarchical level lower than a hierarchical level of the first search word.

Claims

1. A document search apparatus comprising:

a processor programmed to;

receive a plurality of search words in a hierarchical relationship; and

set a first content among a plurality of contents in a hierarchical relationship included in structured document data, as a search range of a first search word;

set a second content at a same hierarchical level as a hierarchical level of the first content or a hierarchical level lower than the hierarchical level of the first content, as a search range of a second search word at a hierarchical level lower than a hierarchical level of the first search word; and

set contents having same attribute information as attribute information of respective search words among the plurality of contents, as search targets of the respective search words.

2. The document search apparatus according to claim 1, wherein the processor is programmed to:

acquire a synonym of at least one of the plurality of search words; and

set the second content as a search range at a corresponding hierarchical level for the synonym.

3. The document search apparatus according to claim 2, wherein the processor is programmed to, based on table-of-contents information including information indicating presence or absence of a text for each of the plurality of contents, set the first content and the second content with a content having the text as a search target.

4. The document search apparatus according to claim 2, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output contents obtained by the search in a format of a subtree.

5. The document search apparatus according to claim 2, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output a result of the search to a display in a form allowing tracing contents including the search words according to a hierarchical relationship of the search words used for the search on the structured document data.

6. The document search apparatus according to claim 1, wherein the processor is programmed to, based on table-of-contents information including information indicating presence or absence of a text for each of the plurality of contents, set the first content and the second content with a content having the text as a search target.

7. The document search apparatus according to claim 6, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output contents obtained by the search in a format of a subtree.

8. The document search apparatus according to claim 6, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output a result of the search to a display in a form allowing tracing contents including the search words according to a hierarchical relationship of the search words used for the search on the structured document data.

9. A non-transitory computer readable medium storing a program causing a computer to function as the processor of the document search apparatus according to claim 6.

10. The document search apparatus according to claim 1, wherein the processor is programmed to, based on table-of-contents information including information indicating presence or absence of a text for each of the plurality of contents, set the first content and the second content with a content having the text as a search target.

11. The document search apparatus according to claim 1, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output contents obtained by the search in a format of a subtree.

12. The document search apparatus according to claim 1, wherein the processor is programmed to:

execute a search on the structured document data with the first content and the second content as search targets; and

output a result of the search to a display in a form allowing tracing contents including the search words according to a hierarchical relationship of the search words used for the search on the structured document data.

13. A non-transitory computer readable medium storing a program causing a computer to function as the processor of the document search apparatus according to claim 1.

14. A non-transitory computer readable medium storing a program causing a computer to function as the processor of the document search apparatus according to claim 2.

15. A document search method comprising:

receiving, by a processor, a plurality of search words in a hierarchical relationship;

setting, by the processor, a first content among a plurality of contents in a hierarchical relationship included in structured document data, as a search range of a first search word;

setting, by the processor, a second content at a same hierarchical level as a hierarchical level of the first content or a hierarchical level lower than the hierarchical level of the first content, as a search range of a second search word at a hierarchical level lower than a hierarchical level of the first search word; and

setting, by the processor, contents having same attribute information as attribute information of respective search words among the plurality of contents, as search targets of the respective search words.
