19. A computer-implemented method, comprising: identifying a plurality of structured documents and distinct metadata for each structured document, the structured documents having a same structured data format, wherein the structured documents are received from one or more data sources and the distinct metadata for each structured document is received from one or more data sources different from the one or more data sources from which the structured document was received; wherein the same structured data format is a format for geographic data, wherein the plurality of structured documents contain location names, descriptive text, and geographic references; parsing each structured document in the plurality of structured documents and extracting a plurality of data sets from each structured document; merging the distinct metadata from the one or more data sources, including removing duplicate distinct metadata; associating the distinct metadata for each structured document with each data set extracted from the structured document; adding a plurality of record items to a searchable database, wherein a structure of the record items corresponds to the same structured data format of the structured documents, wherein each record item corresponds to one of the extracted data sets, and wherein each record item is associated with the distinct metadata associated with the corresponding data set; receiving a search query; using the distinct metadata associated with each of one or more of the record items to identify at least one record item in the searchable database; and returning the identified at least one record item in response to the search query.
23. The method of claim 19 , further comprising calculating a query independent score for each data set from the metadata associated with the structured document from which the data set was extracted.
