Finders are available to help facilitate selections and control vocabulary usage, thus improving result outputs.  At times the potential list of selections can be quite extensive, and the finders help users make selections from large lists.  Multiple selections can be made when utilizing finders during a query.

The MHC Allele Finder facilitates the selection of one or more MHC alleles.  Initially the Allele Finder lists all alleles ordered by allele name.  The Allele Finder allows the user to find alleles by organism, class {I, II, non-classical}, and allele in the Find box (see Figure below).  After the user supplies their search criteria and clicks the Search button, the system will filter the list of MHC alleles using the organism, class, and allele provided.  The allele finder uses wild card characters by default on both ends of criteria entered into the allele field.  The system then returns any alleles that contain the value in the name field and match the class selected.
