Abstract
Data records are searched by use of a taxonomy comprising search terms having associated respective metadata wherein, for each search term, the associated metadata includes a measure of relatedness based on co-occurrences of search terms in at least one data record of a body of data records. A set of one or more search terms is selected and the taxonomy is referred to so as to extend the set of one or more selected search terms by including any different search terms having a significant measure of relatedness in relation to the one or more selected search terms.

A search engine for searching data record by use of a taxonomy comprising search terms having associated respective metadata wherein, for each search term, the associated metadata includes a measure of relatedness based on co-occurrences of search terms in at least one data record of a body of data records, the search engine comprising:
- i) a search term selector for selecting a set of one or more search terms;
- and
- ii) a search strategy formulator configured to access the taxonomy to formulate a search strategy by extending the set of one or more selected search terms by including any different search terms identified by associated metadata as having a significant measure of relatedness in relation to the one or more selected search terms.
