Abstract

The invention provides a session-based bi-directional multi-tier client-server asynchronous information database search and retrieval system for sending a character-by-character string of data to an intelligent server that can be configured to immediately analyze the lengthening string character-by-character and return to the client increasingly appropriate database information as the client sends the string.

Claims

1. A method, comprising:

automatically detecting;

on a client computer, modification by a user of a search query for content from one or more remote content sources in an entry field;

sending a request message containing a string representing an incomplete version of the search query over a network to a server system comprising one or more computers serving a plurality of client computers,

receiving, by the server system, the string;

matching, by the server system, the string to entries in a cache of queries and search results previously retrieved from one or more content sources;

retrieving, by the server system, data indicative of the search results matching the incomplete version of the search query;

asynchronously sending, by the server system to the client computer a message containing at least a portion of the data indicative of the search results;

receiving, on the client computer, the message; and

displaying at least a portion of the data indicative of the search results on the client computer.

2. The method of claim 1,

wherein the entry field is displayed as part of a HTML page in a web browser on said client computer, and

whereby the result message is received by said client computer without loading a new HTML page.

3. The method of claim 1,

wherein the client computer is a cell phone or a personal organizer and the entry field is part of an application on said client computer.

4. The method of claim 1,

wherein the data indicative of the search results is retrieved from the cache.

5. The method of claim 1,

wherein at least a portion of the data indicative of the search results is retrieved from the one or more content sources.

6. The method of claim 1, wherein retrieving data indicative of the search results comprises:

sending one or more content inquiries to one or more respective content sources; and

receiving at least a portion of the data indicative of the search results in response to the one or more content inquiries.

7. The method of claim 6, wherein, after retrieving the data indicative of the search results, at least a portion of said data is stored in the cache for future use by a plurality of users.

8. The method of claim 1, whereby the client computer adds a qualifier to the query string, and whereby the server system uses said qualifier to retrieve appropriate search results based on both the query string and said qualifier.

9. The method of claim 1, wherein the content sources are one or more of a database, a search and retrieval system, a thesaurus, a reference work, an address book, a control system, a dictionary, an encyclopedia, a products database, a quotes library, a stock quote system, a news service, internet advertisements, a catalog, a complex function, a translation engine, a classification scheme, a lookup list, an auto-complete history, an algorithm, a directory, or a search engine.

10. A system for presenting to a user of a client computer remote search results from a server system consisting of one or more computers, the server system serving a plurality of client computers, comprising:

a server-based cache of queries and search results previously retrieved from one or more content sources;

a client object, in communication with a client software at the client computer, wherein the client object automatically detects modifications by a user of a search query for content from the one or more remote content sources in an entry field and sends over a network request messages containing a string representing consecutive incomplete versions of the search query to the server system;

a server object, in communication with server software on the server system, wherein the server object, in response to receiving each of the consecutive messages from the client system, matches the contained string to entries in the server-based cache, retrieves data indicative of the search results matching contained string, and asynchronously returns messages to the client object, each containing at least a portion of the data indicative of the search results for display of at least a portion thereof on the client computer.

11. The system of claim 10,

wherein the entry field is part of a HTML page in a web browser on said client computer, and

whereby each result message is received by said client computer without loading a new HTML page.

12. The system of claim 10,

wherein the client computer is a cell phone or a personal organizer and the entry field is part of an application on said client computer.

13. The system of claim 10,

wherein the data indicative of the search results is retrieved from the cache.

14. The system of claim 10,

wherein at least a portion of the data indicative of the search results is retrieved from one or more content sources.

15. The system of claim 10, wherein retrieving data indicative of the search results comprises:

sending one or more content inquiries to one or more respective content sources; and

receiving at least a portion of the data indicative of the search results in response to the one or more content inquiries.

16. The system of claim 10,

wherein, after retrieving the data indicative of the search results, at least a portion of said data is stored in the cache.
