15. A system comprising: a first database storing a first data table; a second database storing a second data table; a non-transitory computer readable storage medium storing a table graph comprising: a first node associated with a first data table; a second node associated with a second data table; a first link between the first node and the second node, wherein the first link indicates a first field of the first data table is associated with a first field of the second data table; and a second link between the first node and the second node, wherein the second link indicates a second field of the first data table is associated with a second field of the second data table; and one or more hardware processors configured to execute software instructions in order to: execute a search query on the table graph by at least: looking up first information in the first data table, wherein the first information is associated with the search query; looking up second information in the second data table by reference to the first link, wherein the second information is associated with the first information, and wherein the first and second information together comprise a direct hit of the search query; and looking up third information in the first data table by reference to the second link, wherein the third information is different from the first information, and wherein the third information comprises an indirect hit of the search query; and provide, for display by the system: the third information, and an indication that the third information comprises the indirect hit of the search query.
