Milvex.ExprParams (milvex v0.10.2)

Converts Elixir values to Milvus TemplateValue protobuf structs for filter expression templating.

Filter templates allow parameterized filter expressions using {placeholder} syntax, where values are substituted at query time by Milvus. This improves performance by reducing expression parsing overhead, especially with large arrays or complex expressions.

Supported types

boolean -> bool_val
integer -> int64_val
float -> float_val
string -> string_val
[boolean] -> BoolArray
[integer] -> LongArray
[float] -> DoubleArray
[string] -> StringArray
