Data retrieval system and method

1. A method, performed by one or more processors, comprising:

receiving a user query;

deriving, based on the user query, a search engine query for use with search engine software;

sending, to the search engine software, the search engine query to cause the search engine software to locate first data stored in a search engine index;

receiving, from the search engine software, the first data, the first data comprising one or more data records;

deriving, based on the first data, a data access query for use with data access software for locating second data using data extracted from the one or more data records, the second data comprising one or more data objects;

sending, to the data access software, the data access query to cause the data access software to locate the second data stored in a distributed data store; and

receiving, from the data access software, the second data.

2. The method of claim 1 , wherein the search engine software is distributed search engine software.

3. The method of claim 2 , wherein the search engine index is a distributed inverted index.

4. The method of claim 3 , wherein the data access software comprises a cluster-computing framework.

5. The method of claim 4 , wherein the distributed data store is a distributed database.

6. The method of claim 5 , wherein the search engine index stores a subset of data stored in the distributed data store.

7. The method of claim 6 , wherein the distributed data store comprises first one or more computing devices located at a first data center and second one or more computing devices located at a second data center.

8. The method of claim 7 , further comprising:

in response to receiving the first data, sending the first data to a client device; and

in response to receiving the second data, sending the second data to the client device.

9. The method of claim 8 , wherein the sending the second data is subsequent to the sending the first data.

10. The method of claim 1 , wherein the deriving, based on the user query, a search engine query for use with the search engine software comprises processing the user query to derive one or more first operators in a search engine query format for the search engine query,

wherein the deriving, based on the first data, a data access query for use with data access software comprises processing the user query to derive one or more second operators in a data access query format for the data access query, and wherein each first operator of the one or more first operators is equivalent to a second operator of the one or more second operators.

11. A system comprising:

retrieval software;

a search engine index;

a distributed data store storing a superset of data stored in the search engine index;

search engine software configured to:

receive a search engine query;

in response to receiving the search engine query, locate first data stored in the search engine index; and

send the first data to the retrieval software; and

data access software configured to:

receive a data access query;

in response to receiving the data access query, locate second data stored in the distributed data store; and

send the second data to the retrieval software

wherein the retrieval software is configured to:

send, to the search engine software, the search engine query;

receive, from the search engine software, the first data, wherein the first data comprises one or more data records;

derive, based on the one or more data records, the data access query for locating one or more data objects derived using data extracted from the one or more data records;

send, to the data access software, the data access query; and

receive, from the data access software, the second data comprising the one or more data objects.

12. The system of claim 11 , wherein the one or more data objects are rich data objects defined using an ontology.

13. The system of claim 12 , wherein the one or more data records are log records.

14. The system of claim 11 , wherein the retrieval software is further configured to:

receive a user query;

derive, based on the user query, the search engine query for use with the search engine software and the data access query for use the with data access software by at least:

processing the user query to derive one or more first operators in a search engine query format for the search engine query; and

processing the user query to derive one or more second operators in a data access query format for the data access query,

wherein each first operator of the one or more first operators is equivalent to a second operator of the one or more second operators.

15. The system of claim 11 , wherein the retrieval software is further configured to:

in response to receiving the first data, send the first data to a client device; and

in response to receiving the second data, send the second data to the client device.

16. The system of claim 11 , further comprising:

a client device configured to:

send, to the retrieval software, the user query;

receive, from the retrieval software, the first data;

in response to receiving the first data, display the first data;

receive, from the retrieval software, the second data; and

in response to receiving the second data, display the second data.

17. The system of claim 16 , wherein the client device is further configured to receive and display the second data subsequent to receiving and displaying the first data.

18. The system of claim 17 , wherein the distributed data store comprises first one or more computing devices located at a first data center and second one or more computing devices located at a second data center.

19. A non-transitory computer readable medium storing a computer program, which when executed by one or more processors of a data processing apparatus cause the data processing apparatus to carry out a method according to claim 1 .
