Optional. The filter applied to the returned list.
We only support filtering for the `deployed_image_index.image_index` field.
However, to filter by a corpus instead of an image index, simply use
`deployed_image_index.corpus`, which will return all endpoints with
`deployed_image_index.image_index` inside of the given corpus.
A basic filter on image index would look like:
  deployed_image_index.image_index =
    "projects/123/locations/us-central1/corpora/my_corpus/imageIndexes/my_image_index"
A basic filter on corpus would look like:
  deployed_image_index.corpus =
    "projects/123/locations/us-central1/corpora/my_corpus"

<code>string filter = 4 [(.google.api.field_behavior) = OPTIONAL];</code>

@return The bytes for filter.
