Sort order of search results: what logic is used to order the entries returned by a search?
There are 18 fields by which the database entries are indexed. They can be seen in the drop-down list in the center of the Preview/Index page. Search results are sorted depending on where (in which field), and how many times the word or phrase appears in the entry. Each appearance of the word contributes a number of points to the score used for sorting. Some fields are valued more than others: • title word field is preferred most: 200 points per appearance • clinical synopsis and gene map disorder: 10 points per appearance • text word and allelic variants: 3 points per appearance • reference (Authors and titles of citations): 1 point per appearance For simplicity, the described scheme does not include numerical terms like MIM numbers, genemap loci, etc. They also have their own fields and scores. Additional factors that affect the score include field specifiers, Boolean operators, and the presence of a search term in a list of important phrases: • if you explicitly specify search field
