ABSTRACT:
Searching a database involves creating an access structure including a first tree data structure having a root node and at least one child node. Each child node is associated with match data corresponding to a data value of a field of a database record. Leaf child nodes of the first tree data structure include a link to another tree data structure in the access structure. Leaf child nodes of a further tree data structure include a link to a database record. The tree structures are traversed and scores are computed for the paths traversed that reflect the level of matching between the match pattern data of the nodes in a path and a search request to identify a database record that best matches the request.
