Abstract
A search apparatus (1) coupled to a database, the apparatus (1) comprising: a processor configured to execute instructions; a memory storing instructions which, when executed by the processor, cause the processor to: search the database for items containing a search term, wherein items containing the search term are matched items; identify fields corresponding to attributes of the matched items; define a range of values for each field; divide the range of values for each field into a plurality of ranged field buckets; distribute the matched items between the ranged field buckets based on attributes of the matched items that are within the range of values for each ranged field bucket; calculate an effectiveness value for each field based on the number of matched items in each of the ranged field buckets; select one or more top fields, each top field having an effectiveness value that is greater than a predetermined effectiveness value; and provide an effectiveness indicator output which is indicative of the effectiveness of each top field such that a user can use the effectiveness indicator output to select a top field for use as a filter in a further search.
