Abstract
An approach is provided that search unstructured data sources with a search engine using initial search terms. Search hits received from the search engine are gathered and possible search terms are retrieved from the search hits. Entities are extracted from the search hits where the entities correspond to the extracted terms. The extracted entities and terms that are extracted are used to query structured data sources, such as tables in a relational database. Query results are then received from the queries performed on the structured data sources. These query results are used to further search the unstructured data sources to again receive search hits from which terms and entities are extracted. Search hits and the extracted entities are stored in a results data store for analysis.
