1. A computer-implemented method, comprising: at a query converter running on a processor, identifying a first set of fields in unstructured data by querying an unstructured data source, the unstructured data source comprising text records, the querying initiated to obtain field identification data from the unstructured data source, each of the fields in the first set of fields corresponding to a portion of text extracted from a portion of at least one of the text records that is smaller than the text records; receiving, at the query converter, a structured query corresponding to a structured query language; using the identified first set of fields, converting the structured query into an unstructured query corresponding to an unstructured query language associated with accessing the unstructured data; initiating a search on the unstructured data using the unstructured query; and returning results of the search.
