INCREASING SEARCH RESULT VALIDITY

Methods, search platforms, systems, and storage media for handling queries in a database system. The database system includes at least one client and at least one search platform. The search platform maintains pre-collected search results which are associated which confidence factors. A confidence factor indicates a probability of the associated pre-collected search result being valid. The search platform receives a query indicating at least one search criterion to the search platform. The confidence factors associated with the identified pre-collected search results are utilized to increase the mean probability of pre-collected search results returned to the client. For example, pre-collected search results complying with the at least one search criterion and being associated with confidence factors having values exceeding a given threshold are returned to the client.
