Important: Don't explain how to construct the filter - use the specified operators and fields to search the content and return relevant results.
If 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.

Basic Comparison Operators:
- $eq: Exact match (default when using field: value)
  Example: { "category": "electronics" }
- $ne: Not equal
  Example: { "category": { "$ne": "electronics" } }
- $gt: Greater than
  Example: { "price": { "$gt": 100 } }
- $gte: Greater than or equal
  Example: { "price": { "$gte": 100 } }
- $lt: Less than
  Example: { "price": { "$lt": 100 } }
- $lte: Less than or equal
  Example: { "price": { "$lte": 100 } }

Array Operators:
- $in: Match any value in array
  Example: { "category": { "$in": ["electronics", "books"] } }
- $nin: Does not match any value in array
  Example: { "category": { "$nin": ["electronics", "books"] } }
- $all: Match all values in array
  Example: { "tags": { "$all": ["premium", "sale"] } }

Logical Operators:
- $and: Logical AND (can be implicit or explicit)
  Implicit Example: { "price": { "$gt": 100 }, "category": "electronics" }

- $or: Logical OR
  Example: { "$or": [{ "price": { "$lt": 50 } }, { "category": "books" }] }

export const UPSTASH_PROMPT = `When querying Upstash Vector, you can ONLY use the operators listed below. Any other operators will be rejected.
Important: Don't explain how to construct the filter - use the specified operators and fields to search the content and return relevant results.
If 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.

Basic Comparison Operators:
- $eq: Exact match (default when using field: value)
  Example: { "category": "electronics" } or { "category": { "$eq": "electronics" } }
- $ne: Not equal
  Example: { "category": { "$ne": "electronics" } }
- $gt: Greater than
  Example: { "price": { "$gt": 100 } }
- $gte: Greater than or equal
  Example: { "price": { "$gte": 100 } }
- $lt: Less than
  Example: { "price": { "$lt": 100 } }
- $lte: Less than or equal
  Example: { "price": { "$lte": 100 } }

Array Operators:
- $in: Match any value in array
  Example: { "category": { "$in": ["electronics", "books"] } }
- $nin: Does not match any value in array
  Example: { "category": { "$nin": ["electronics", "books"] } }
- $all: Matches all values in array
  Example: { "tags": { "$all": ["premium", "new"] } }

Logical Operators:
- $and: Logical AND (implicit when using multiple conditions)
  Example: { "$and": [{ "price": { "$gt": 100 } }, { "category": "electronics" }] }
- $or: Logical OR
  Example: { "$or": [{ "price": { "$lt": 50 } }, { "category": "books" }] }
- $not: Logical NOT
  Example: { "$not": { "category": "electronics" } }
- $nor: Logical NOR
  Example: { "$nor": [{ "price": { "$lt": 50 } }, { "category": "books" }] }

Element Operators:
- $exists: Check if field exists
  Example: { "rating": { "$exists": true } }

Special Operators:
- $regex: Pattern matching using glob syntax (only as operator, not direct RegExp)
  Example: { "name": { "$regex": "iphone*" } }
- $contains: Check if array/string contains value
  Example: { "tags": { "$contains": "premium" } }

Restrictions:
- Null/undefined values are not supported in any operator
- Empty arrays are only supported in $in/$nin operators
- Direct RegExp patterns are not supported, use $regex with glob syntax
- Nested fields are supported using dot notation
- Multiple conditions on same field are combined with AND
- String values with quotes are automatically escaped
- Only logical operators ($and, $or, $not, $nor) can be used at the top level
- All other operators must be used within a field condition
  Valid: { "field": { "$gt": 100 } }
  Valid: { "$and": [...] }
  Invalid: { "$gt": 100 }
- $regex uses glob syntax (*, ?) not standard regex patterns
- $contains works on both arrays and string fields
- Logical operators must contain field conditions, not direct operators
  Valid: { "$and": [{ "field": { "$gt": 100 } }] }
  Invalid: { "$and": [{ "$gt": 100 }] }
- $not operator:
  - Must be an object
  - Cannot be empty
  - Can be used at field level or top level
  - Valid: { "$not": { "field": "value" } }
  - Valid: { "field": { "$not": { "$eq": "value" } } }
- Other logical operators ($and, $or, $nor):
  - Can only be used at top level or nested within other logical operators
  - Can not be used on a field level, or be nested inside a field
  - Can not be used inside an operator
  - Valid: { "$and": [{ "field": { "$gt": 100 } }] }
  - Valid: { "$or": [{ "$and": [{ "field": { "$gt": 100 } }] }] }
  - Invalid: { "field": { "$and": [{ "$gt": 100 }] } }
  - Invalid: { "field": { "$or": [{ "$gt": 100 }] } }
  - Invalid: { "field": { "$gt": { "$and": [{...}] } } }
Example Complex Query:
{
  "$and": [
    { "category": { "$in": ["electronics", "computers"] } },
    { "price": { "$gt": 100, "$lt": 1000 } },
    { "tags": { "$all": ["premium", "new"] } },
    { "name": { "$regex": "iphone*" } },
    { "description": { "$contains": "latest" } },
    { "$or": [
      { "brand": "Apple" },
      { "rating": { "$gte": 4.5 } }
    ]}
  ]

Restrictions:
- Regex patterns are not supported
- Logical operators are not supported
- Element operators are not supported
- Fields must have a flat structure, as nested fields are not supported
- Multiple conditions on the same field are supported
- Empty arrays in $in/$nin will return no results
- Filter keys cannot be longer than 512 characters
- Filter keys cannot contain invalid characters ($, ", empty)
- Filter size is limited to prevent oversized queries
- Invalid types in operators return no results instead of throwing errors
- Empty objects are accepted in filters
- Metadata must use flat structure with dot notation (no nested objects)
- Must explicitly create metadata indexes for filterable fields (limit 10 per index)
- Can only effectively filter on indexed metadata fields
- Metadata values can be strings, numbers, booleans, or homogeneous arrays
- No operators can be used at the top level (no logical operators supported)
- All operators must be used within a field condition
