Abstract

A system and method for providing full text searching of content within a content management system are disclosed. A repository can maintain content in a plurality of nodes of various content types that have binary as well as metadata properties. An abstracted application programming interface can be provided for constructing full text search queries based on the metadata and the binary properties of the various node types. The abstracted interface can allow a search engine to be replaced with another engine without altering the functionality of the virtual content repository. A search index can be generated by the search engine in order to enable faster querying of content. The search engine can also subscribe to a set of federated event listeners that provide notifications of various operations within the content repository to the search engine, such that the index can be appropriately maintained and updated by the search engine.

Claims

1. A computer implemented method for providing full text searching of content within a content management system, said method comprising:

storing content in a content repository, said repository including one or more nodes, each node of one or more types containing one or more of binary properties and metadata properties;

generating a search index by a search engine in order to reflect said content within the content repository;

registering said search engine with one or more federated event listeners, said event listeners providing, to said search engine, notifications of operations occurring within the content repository; and

updating the search index by the search engine based upon input from said one or more federated event listeners.

2. The method according to claim 1, further comprising:

constructing a search query by a client, wherein one or more clauses of said search query is based on said binary properties and said metadata properties; and

executing the search query by said search engine against the search index.

3. The method according to claim 2 wherein said search query is constructed using an abstracted application programming interface (API) that allows said search engine to be replaced with another search engine while maintaining functionality provided by the content repository.

4. The method according to claim 1 wherein said event listeners providing, to said search engine, notifications of operations occurring within the content repository further includes:

detecting an operation that modifies said one or more content nodes within the content repository; and

dispatching an event by the content repository, said event including associated data for describing said operation.

5. The method according to claim 1 wherein generating said search index by said search engine further includes:

determining whether said one or more types and said metadata properties have been designated as being searchable; and

adding said one or more nodes of said one or more types and node property values to the search index only if they have been designated as searchable.

6. The method according to claim 1 wherein said one or more nodes include a set of system metadata properties and user-defined metadata properties for providing information about each content node.

13. The method according to claim 1 wherein said one or more nodes include a set of system meta data properties and user-defined meta data properties for providing information about each content node.

7. A computer implemented method for providing full text searching of content within a content management system, said method comprising:

maintaining content in a content repository, said repository including one or more nodes, each node of one or more types containing one or more of binary properties and metadata properties;

providing an abstracted application programming interface (API) for forming search queries, said abstracted API adapted to plug into one or more search engines;

constructing a search query by a client using said abstracted API wherein one or more clauses of said search query is based on said one or more of binary properties and metadata properties; and

executing said search query by said search engine and returning a result set to said client.

8. The method according to claim 7 further including:

generating a search index by a search engine in order to reflect said content within the content repository, said search query executed against said search index.

9. The method according to claim 8 wherein executing said search query and returning the result set to said client further includes:

translating said result set from the search index to said one or more nodes within the content repository.

10. The method according to claim 8 wherein generating said search index by the search engine further includes:

determining whether said one or more types and said metadata properties have been designated as being searchable; and

adding said one or more nodes of said one or more types and node property values to the search index only if they have been designated as searchable.

11. The method according to claim 7 wherein said abstracted API allows said search engine to be replaced with another search engine while maintaining fuinctionality provided by the content repository.

12. The method according to claim 7 wherein said search query includes a combination of a string for searching within said one or more binary properties and a meta data expression for searching within said one or more meta data properties.

14. A system for providing full text searching of content within a content management system, said system comprising:

a content repository including one or more nodes, each node of one or more types that contain one or more binary properties and metadata properties;

an abstracted application programming interface (API) for constructing one or more search queries based upon said binary properties and said meta data properties; and

a search engine that executes said one or more search queries and returns a result set.

15. The system according to claim 14, further comprising:

a search index generated by said search engine based on said one or more nodes in the repository wherein said one or more search queries are executed against the search index.

16. The system according to claim 15 wherein said result set is translated from the search index to said one or more nodes within the content repository.

17. The system according to claim 15 wherein data associated with said one or more nodes is added to the search index only if said one or more types and said metadata properties have been designated as searchable within the content repository in order to limit the size of the search index.

18. The system according to claim 14 wherein said abstracted API allows said search engine to be replaced with another search engine while maintaining functionality provided by the content repository.

19. The system according to claim 14 wherein said search query includes a combination of a string for searching within said one or more binary properties and a meta data expression for searching within said one or more meta data properties.

20. A computer readable medium having instructions stored thereon, which when executed by one or more processors cause a system to:

store content in a content repository, said repository including one or more nodes, each node of one or more types containing one or more of binary properties and metadata properties;

generate a search index by a search engine in order to reflect said content within the content repository;

register said search engine with one or more federated event listeners, said event listeners providing, to said search engine, notifications of operations occurring within the content repository; and

update the search index by the search engine based upon input from said one or more federated event listeners.
