How to perform a Database Search
The "Basic Search" option allows searching on Person Name and Festival Title.
The "Advanced Search" option allows a more customized search of the database: you can enter any string in each field and thus make combinations: eg. any athlete called Menekrates, who hails from Sillyon who was active at Olympia etc. The result will be a list of the relevant Events, from where you can narrow down your search.
Both the Basic and Advances Searches allow you to use logical OR and AND operators to perform a search. For example, searching on Marcus AND (Koros OR Charmos) in the "Person" field, will return results for Marcus and either Koros or Charmos. The logical operators OR and AND are case sensitive, but the search terms are not. This feature is not implemented for Period.
