export declare const UPSTASH_PROMPT = "When querying Upstash Vector, you can ONLY use the operators listed below. Any other operators will be rejected.\nImportant: Don't explain how to construct the filter - use the specified operators and fields to search the content and return relevant results.\nIf a user tries to give an explicit operator that is not supported, reject the filter entirely and let them know that the operator is not supported.\n\nBasic Comparison Operators:\n- $eq: Exact match (default when using field: value)\n  Example: { \"category\": \"electronics\" }\n- $ne: Not equal\n  Example: { \"category\": { \"$ne\": \"electronics\" } }\n- $gt: Greater than\n  Example: { \"price\": { \"$gt\": 100 } }\n- $gte: Greater than or equal\n  Example: { \"price\": { \"$gte\": 100 } }\n- $lt: Less than\n  Example: { \"price\": { \"$lt\": 100 } }\n- $lte: Less than or equal\n  Example: { \"price\": { \"$lte\": 100 } }\n\nArray Operators:\n- $in: Match any value in array\n  Example: { \"category\": { \"$in\": [\"electronics\", \"books\"] } }\n- $nin: Does not match any value in array\n  Example: { \"category\": { \"$nin\": [\"electronics\", \"books\"] } }\n\nLogical Operators:\n- $and: Logical AND (can be implicit or explicit)\n  Implicit Example: { \"price\": { \"$gt\": 100 }, \"category\": \"electronics\" }\n  Explicit Example: { \"$and\": [{ \"price\": { \"$gt\": 100 } }, { \"category\": \"electronics\" }] }\n- $or: Logical OR\n  Example: { \"$or\": [{ \"price\": { \"$lt\": 50 } }, { \"category\": \"books\" }] }\n\nElement Operators:\n- $exists: Check if field exists\n  Example: { \"rating\": { \"$exists\": true } }\n\nRestrictions:\n- Regex patterns are not supported\n- Only $and and $or logical operators are supported at the top level\n- Empty arrays in $in/$nin will return no results\n- Nested fields are supported using dot notation\n- Multiple conditions on the same field are supported with both implicit and explicit $and\n- At least one key-value pair is required in filter object\n- Empty objects and undefined values are treated as no filter\n- Invalid types in comparison operators will throw errors\n- All non-logical operators must be used within a field condition\n  Valid: { \"field\": { \"$gt\": 100 } }\n  Valid: { \"$and\": [...] }\n  Invalid: { \"$gt\": 100 }\n- Logical operators must contain field conditions, not direct operators\n  Valid: { \"$and\": [{ \"field\": { \"$gt\": 100 } }] }\n  Invalid: { \"$and\": [{ \"$gt\": 100 }] }\n- Logical operators ($and, $or):\n  - Can only be used at top level or nested within other logical operators\n  - Can not be used on a field level, or be nested inside a field\n  - Can not be used inside an operator\n  - Valid: { \"$and\": [{ \"field\": { \"$gt\": 100 } }] }\n  - Valid: { \"$or\": [{ \"$and\": [{ \"field\": { \"$gt\": 100 } }] }] }\n  - Invalid: { \"field\": { \"$and\": [{ \"$gt\": 100 }] } }\n  - Invalid: { \"field\": { \"$or\": [{ \"$gt\": 100 }] } }\n  - Invalid: { \"field\": { \"$gt\": { \"$and\": [{...}] } } }\n\nExample Complex Query:\n{\n  \"$and\": [\n    { \"category\": { \"$in\": [\"electronics\", \"computers\"] } },\n    { \"price\": { \"$gte\": 100, \"$lte\": 1000 } },\n    { \"rating\": { \"$exists\": true, \"$gt\": 4 } },\n    { \"$or\": [\n      { \"stock\": { \"$gt\": 0 } },\n      { \"preorder\": true }\n    ]}\n  ]\n}";
