Abstract

A method and system for searching a collaborative document database. The method comprises the steps of providing parent documents and child documents in said database; and for each parent document, building an index document listing a portion of said child documents. The method comprises the further steps of providing a search term, and searching all said index documents for said search term. Preferably, each child document is related to at least one of the parent documents; and the building step includes the step of identifying in the index document for each parent document, at least some of the child documents related to the parent document. With this embodiment, the searching step may include the step of, for each parent document, searching for the search term in the child documents identified in the index document for the parent document.

Claims

1. A method of searching a collaborative document database, comprising the steps of:

providing said database with a plurality of parent documents and a plurality of child documents, each of said child documents being related to at least one of the parent documents in said database;

for each of the parent documents, combining said parent document and the child documents related to said parent document, into a master index document and storing the master index documents in an index document database separate from the collaborative document database, including

i) taking selected field items from the parent document;

ii) placing said selected field items as fields on the index document;

iii) proceeding through the parent document and taking all text thereon and placing said all text from said parent document in said fields of the index document; and

iv) proceeding through said related child documents, obtaining all text from each of said related child documents, and concatenating said all text from said related child documents to data in a search text block field of the index document;

providing a search term; and

searching all said index documents for said search term.

2. A method according to claim 1, wherein:

the combining step includes the step of identifying in the index document for each parent document, at least some of the child documents related to the parent document.

3. A method according to claim 2, wherein the searching step includes the step of, for each parent document, searching for the search term in the child documents identified in the index document for the parent document.

4. A method according to claim 2, wherein the identifying step includes the step of identifying in the index document for each parent document, all of the child documents related to the parent document.

5. A method according to claim 2, wherein the identifying step includes the step of identifying in the index document for each parent document, only the child documents that both are related to the parent document and meet predefined criteria.

6. A method according to claim 1, wherein:

the combining step includes the step, for each parent document, updating the index document for the parent document whenever one of the child documents related to the parent document changes; and

the search term includes a plurality of words.

7. A system for searching a collaborative document database, comprising:

means for providing said database with a plurality of parent documents and a plurality of child documents, each of said child documents being related to at least one of the parent documents;

means for combining for each parent document, said parent document and the child documents related to said parent document, into a master index document, including

i) means for taking selected field items from the parent document

ii) means for placing said selected field items as fields on the index document;

iii) means for proceeding through the parent document and taking all text thereon and placing said all text from said parent document in said fields of the index document; and

iv) means for proceeding through said related child documents, obtaining all text from each of said related child documents, and concatenating said all text from said related child documents to data in a search text block field of the index document;

an index document database separate from the collaborative document database for storing the master index documents;

means far providing a search term; and

means for searching all said index documents for said search term.

8. A system according to claim 7, wherein:

the combining means includes the means for identifying in the index document for each parent document, at least some of the child documents related to the parent document.

9. A system according to claim 8, wherein the searching means includes means for searching, for each parent document, for the search term in the child documents identified in the index document for the parent document.

10. A system according to claim 8, wherein the identifying means includes the means for identifying in the index document for each parent document, all of the child documents related to the parent document.

11. A system according to claim 8, wherein the identifying means includes means for identifying in the index document for each parent document, only the child documents that both are related to the parent document and meet predefined criteria.

12. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for searching a collaborative document database, said method steps comprising:

providing said database with a plurality of parent documents and a plurality of child documents, ach of said child documents being related to at least one of the parent documents;

for each of the parent documents, combining said parent document and the child documents related to said parent document, into a master index document and storing the master index documents in an index document database separate from the collaborative document database, including

i) taking selected field items from the parent document;

ii) placing said selected field items as fields on the index document;

iii) proceeding through the parent document and taking all text thereon and placing said all text from said parent document in said fields of the index document; and

iv) proceeding through said related child documents, obtaining all text from each of said related child documents, and concatenating said all text from said related child documents to data in a search text block field of the index document;

providing a search term; and

searching all said index documents far said search term.

13. A program storage device according to claim 12, wherein:

the combining step includes the step of identifying in the index document for each parent document, at least some of the child documents related to the parent document.

14. A program storage device according to claim 13, wherein the searching step includes the step of, for each parent document, searching for the search term in the child documents identified in the index document for the parent document.
