`DenseVectorField` f
All parsers return scores for retrieved documents that are the approximate
distance to the target vector (defined by the similarityFunction configured at
indexing time) and both support "Pre-Filtering" the document graph to reduce
the number of candidate vectors evaluated (without needing to compute their
vector similarity distances).
+While field queries and bounded range queries are not supported on
`DenseVectorField`, existence queries such as `vector:*` (or the equivalent
`vector:[* TO *]`) can be used to match documents that have a value for the
vector field.

Common parameters for all query parsers are:
