(Otherwise probably all properties should have index in the database)\r\n\r\nAny 'hacky' method is welcome, too!\r\n\r\nBy the way I've seen this very old issue #22 but it seems very old and forgotten. Maybe the new visitors see this issue better.\r\n\r\nThanks.","author":{"url":"https://github.com/ASADeveloper","@type":"Person","name":"ASADeveloper"},"datePublished":"2017-09-21T10:56:13.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/71/LinqToQuerystring/issues/71"}
