    - wherein each result consists of one or more of a string, key, fetch time, expiration time, metadata, logical link to other data sources, or a Uniform Resource Identifier.
  - 17. The system of claim 1, wherein the client object determines the usability of each server system response by comparing an original input to a then-current input;
    - andwherein the client object deems the results usable if they match.
  - 18. The system of claim 1, wherein the query message sent to the server system includes a request identification that is included by the server system in the corresponding server response message.
  - 19. The system of claim 18, wherein the usability of a server system response is determined by the client object by matching the request identification received in the server response message against a request identification on the client.
  - 20. The system of claim 1, wherein the client object caches results received from the server system and reuses said cached results when Previously Presented queries match queries contained in the cache or if cached query results can be filtered to match the Previously Presented queries, instead of sending messages representing those Previously Presented queries to the server system.
  - 21. The system of claim 1, wherein one or more filters are used to validate or transform the input string using a type, pattern, or minimum length;
    - andwherein no query is performed if the input string is found not to conform to or does not transform using said type, pattern, or minimum length.
  - 22. The system of claim 1, wherein the server system is capable of returning results from multiple data sources;
    - wherein the client object selects which of the available data sources at the server system is to be queried; and
