Abstract

A session-based client-server asynchronous information search and retrieval system for sending character-by-character or multi-character strings of data to an intelligent server, that can be configured to immediately analyze the lengthening string and return to the client increasingly appropriate search information. Embodiments include integration within an Internet, web or other online environment, including applications for use in interactive database searching, data entry, online searching, online purchasing, music purchasing, people-searching, and other applications. In some implementations the system may be used to provide dynamically focused suggestions, auto-completed text, or other input-related assistance, to the user.

Claims

1. A system for enabling searches of content at a server, comprising:

a server which is configured to receive queries from clients for content;

a communication protocol which enables an asynchronous connection between the clients and the server, and allows each client to communicate, under control of a user and as part of a session, a plurality of consecutive query strings to query the server for content; and

a query and result cache that stores one or more query strings previously communicated from the clients, or content results previously returned from the server;

wherein each of the clients provides an input field, which allows the user to enter as an input a query comprised of a plurality of consecutive query strings, and wherein the client transmits to the server within the session a plurality of queries to retrieve content from the server matching or related to the plurality of consecutive query strings, wherein each of the plurality of queries form an increasingly lengthening query string for retrieving content from the server; and

wherein the server receives the plurality of queries from the requesting client, and in response to receiving each of one or more additional characters in the increasingly lengthening query string as they are being entered at the input field,

automatically matches the increasingly lengthening query string initially by matching the query string against the content of the query and result cache, and subsequently by matching the query string against other content available to the server, and

asynchronously returns, while the increasingly lengthening query string is being entered by the user at the input field at the client, increasingly relevant content to the client.

2. The system of claim 1, further comprising a web browser at the client for allowing the user to create a plurality of queries, wherein the plurality of queries are entered into the web-based interface by the user to form an increasingly lengthening query string for retrieving content from the server, and wherein the client and the server communicate via the Internet using a hypertext transfer protocol.

3. The system of claim 1, wherein each of the plurality of queries are a single additional character to be added to the increasingly lengthening query string.

4. The system of claim 1, wherein each of the plurality of queries are a plurality of additional characters to be added to the increasingly lengthening query string.

5. The system of claim 1, further compromising a connection to one or more content engines, each using a communication protocol native to said content engine, whereby said content engines are queried if the query and result cache contains no matches for the user query, and whereby the results from these content engines queries are merged and returned to the client.

6. The system of claim 1, wherein the system is provided as a people-searching system, and wherein the server is configured to receive requests from clients for people-searching content.

7. The system of claim 1, wherein the server is configured to receive requests from clients for product-related information.

8. The system of claim 1, wherein the system is provided as a system for searching for documents in full-text databases.

9. The system of claim 1, wherein said clients accumulate a plurality of single characters as they are entered into the client, before sending the plurality of said single characters joined together as one of the plurality of consecutive query strings, to said server.

10. The system of claim 1, wherein said client or a client software adds an additional qualifier value to the query strings that are passed to the server, and wherein the server can use said qualifier to execute the query on said content engines, and return appropriate results based on both each query string and the qualifier value.

11. The system of claim 1, wherein said content returned by the server comprises lists of strings, wherein each string is accompanied by corresponding metadata, and wherein the metadata includes logical links to other data sources or Uniform Resource Identifiers.

12. The system of claim 1, wherein said client input field includes a visual area that contains rotating arrows indicating that queries are being performed, or static symbols that represent the status of the session and the available results while no queries are active.

13. A method for enabling searches of content at a server, comprising the steps of:

providing access to a server which is configured to receive queries from clients for content;

providing a communication protocol which enables an asynchronous connection between the clients and the server, and allows each client to communicate, under control of a user and as part of a session, a plurality of consecutive query strings to query the server for content; and

providing access to a query and result cache that stores one or more query strings previously communicated from the clients, or content results previously returned from the server;

wherein each of the clients provides an input field, which allows the user to enter as an input a query comprised of a plurality of consecutive query strings, and wherein the client transmits to the server within the session a plurality of queries to retrieve content from the server matching or related to the plurality of consecutive query strings, wherein each of the plurality of queries form an increasingly lengthening query string for retrieving content from the server; and

wherein the server receives the queries from one of the clients, and in response to receiving each of one or more additional characters in the increasingly lengthening query string as they are being entered at the input field,

automatically matches the increasingly lengthening query string initially by matching the query string against the content of the query and result cache, and subsequently by matching the query string against other content available to the server, and

asynchronously returns, while the increasingly lengthening query string is being entered by the user at the input field at the client, increasingly relevant content to the client.

14. The method of claim 13, further comprising providing a web browser at the client for allowing the user to create a plurality of queries, wherein the plurality of queries are entered into the web-based interface by the user to form an increasingly lengthening query string for retrieving content from the server, and wherein the client and the server communicate via the Internet using a hypertext transfer protocol.

15. The method of claim 13, wherein each of the plurality of queries are a single additional character to be added to the increasingly lengthening query string.

16. The method of claim 13, wherein each of the plurality of queries are a plurality of additional characters to be added to the increasingly lengthening query string.

17. The method of claim 13, wherein the system is provided as a people-searching system, and wherein the server is configured to receive requests from clients for people-searching content.

18. The method of claim 13, wherein the server is configured to receive requests from clients for product-related information.

19. The method of claim 13, wherein the system is provided as a system for searching for documents in full-text databases.

20. A non-transitory computer readable medium, including instructions stored thereon which when read and executed cause the computer to perform the steps comprising:

providing access to a server which is configured to receive queries from clients for content;

providing a communication protocol which enables an asynchronous connection between the clients and the server, and allows each client to communicate, under control of a user and as part of a session, a plurality of consecutive query strings to query the server for content; and

providing access to a query and result cache that stores one or more query strings previously communicated from the clients, or content results previously returned from the server;

wherein each of the clients provides an input field, which allows the user to enter as an input a query comprised of a plurality of consecutive query strings, and wherein the client transmits to the server within the session a plurality of queries to retrieve content from the server matching or related to the plurality of consecutive query strings, wherein each of the plurality of queries form an increasingly lengthening query string for retrieving content from the server; and

wherein the server receives the queries from one of the clients, and in response to receiving each of one or more additional characters in the increasingly lengthening query string as they are being entered at the input field,

automatically matches the increasingly lengthening query string initially by matching the query string against the content of the query and result cache, and subsequently by matching the query string against other content available to the server, and

asynchronously returns, while the increasingly lengthening query string is being entered by the user at the input field at the client, increasingly relevant content to the client.
