Using strict filters on metadata [QnA Maker dialog in Bot Composer ]

[RohitJhander]

We are using qna maker dialog in bot composer to get answers from KB. We need to filter response based on metadata field set in QnA. For this we are using Strict Filters option available in Bot Composer. We checked in schema.sdk, strict filters accept static string values for metadata but we want to do filtering based on some value stored in memory variable (ex. $user). For this we tried changing schema and set type for metadata value as reference. But this approached didn't work. Pls suggest any ideas for the same.
