Abstract
Described herein are various technologies pertaining to provision of query suggestions to a user independent of a query log. Key phrases are automatically identified in documents of a document corpus, and a forward index and inverted index are generated. The forward index indexes key phrases by documents, and the inverted index indexes documents by key phrases. A query is received from a user, and documents relevant to the query are retrieved. Key phrases in the retrieved documents are identified via the forward index, and a subset of the key phrases are selected as query suggestions by determining coverage of the key phrases as identified in the inverted index.
