caDSR Freestyle Search performs what is sometimes called a soft or fuzzy search; the search terms and phrases are not required to exactly match items in the database for a match to be found.

When matches are found the results are assigned a numerical weight which includes the order of the match, the number of terms matched, the Administered Item type, Workflow Status and Registration Status.

Results are returned sorted in descending order with the heaviest (highest value) weight first. The various search options dynamically alter the weights.
