ABSTRACT
An increasing number of data sets are being published online, in institutional or government repositories as well as by individual researchers, journalists, and others. These data are often represented as tables of various kinds: however, repositories have poor search over and inside tables. It is difficult for a user to tell from a repository's portal whether a useful dataset is available, and this problem is only likely to get worse.
We describe this problem, and demonstrate that the naïve approach of full-text search is not appropriate. We describe an alternative, based on inferring types of data and indexing columns as a unit, and demonstrate some improvements in early success especially when long captions are not available.
