Techniques for providing semantic search of a data store are disclosed. A similarity metric of a document comprising the data store to a concept represented in a semantic model derived at least in part from a reference source that includes content not included in the data store is determined. A relevance metric of a search query to the concept is computed. The similarity metric and the relevance metric are used to determine, at least in part, a ranking of the document with respect to the search query.

A method, comprising: providing a data store including documents;providing a semantic model including a plurality of concepts, wherein the semantic model is derived at least in part from a reference source that includes content not included in the data store;determining at least one similarity me
1. A method, comprising: providing a data store including documents;providing a semantic model including a plurality of concepts, wherein the semantic model is derived at least in part from a reference source that includes content not included in the data store;determining at least one similarity metric for each document of the plurality of documents, wherein each respective similarity metric represents a similarity between a respective document of the plurality of documents and a respective concept of the plurality of concepts in the semantic model;receiving a search query;computing at least one relevance metric of the search query, wherein each relevance metric represents a relevance of the search query to a respective concept of the plurality of concepts represented in the semantic model; anddetermining a ranking of at least a subset of the plurality of documents with respect to the search query using at least the at least one similarity metric and the at least one relevance metric. 2. The method of claim 1, further comprising using the reference source to build the semantic model. 3. The method of claim 1, further comprising using the semantic model to provide semantic search functionality with respect to a plurality of data stores. 4. The method of claim 1, wherein the reference source comprises a body of content containing items representing a wide range of concepts. 5. The method of claim 1, wherein the reference source comprises an online source of articles on a wide range of subjects. 6. The method of claim 1, wherein the semantic model is stored on a user device. 7. The method of claim 1, wherein determining the at least one similarity metric for each document of the plurality of documents includes embedding each document of the plurality of documents in the semantic model. 8. The method of claim 1, wherein computing the at least one relevance metric includes embedding the search query in the semantic model. 9. The method of claim 1, wherein the data store comprises at least a portion of a file system. 10. The method of claim 1, wherein the data store comprises a set of help topic, product or system knowledge base, or other limited domain articles. 11. A system, comprising: a processor configured to: provide a data store including a plurality of documents;provide a semantic model including a plurality of concepts, wherein the semantic model is derived at least in part from a reference source that includes content not included in the data store;determine at least one similarity metric for each document of the plurality of documents, wherein each respective similarity metric represents a similarity between a respective document of the plurality of documents and a respective concept of the plurality of concepts in the semantic model;receive a search query;compute at least one relevance metric of the search query, wherein each relevance metric represents a relevance of the search query to a respective concept of the plurality of concepts represented in the semantic model; anddetermine a ranking of at least a subset of the plurality of documents with respect to the search query using at least the at least one similarity metric and the at least one relevance metric; and memory coupled to the processor and configured to store the semantic model. 12. The system of claim 11, wherein the semantic model is stored on the system. 13. The system of claim 11, wherein determining the at least one similarity metric for each document of the plurality of documents includes embedding each document of the plurality of documents in the semantic model. 14. The system of claim 11, wherein computing the at least one relevance metric includes embedding the search query in the semantic model. 15. A computer program product, the computer program product being embodied in a tangible, non-transitory computer readable storage medium and comprising computer instructions for: providing a data store including a plurality of documents;providing a semantic model including a plurality of concepts, wherein the semantic model is derived at least in part from a reference source that includes content not included in the data store;determining at least one similarity metric for each document of the plurality of documents wherein each respective similarity metric represents a similarity between a respective document of the plurality of documents and a respective concept of the plurality of concepts in the semantic model;receiving a search query;computing at least one relevance metric of the search query, wherein each relevance metric represents a relevance of the search query to a respective concept of the plurality of concepts represented in the semantic model; anddetermining a ranking of at least a subset of the plurality of documents with respect to the search query using at least the at least one similarity metric and the at least one relevance metric. 16. The computer program product of claim 15, further comprising computer instructions for using the reference source to build the semantic model. 17. The computer program product of claim 15, wherein determining the at least one similarity metric for each document of the plurality of documents includes embedding each document of the plurality of documents in the semantic model. 18. The method of claim 5, wherein the reference source is Wikipedia.
