NAME
gcloud vector-search collections data-objects batch-search - batch search data objects from a Vector Search collection
SYNOPSIS
gcloud vector-search collections data-objects batch-search --collection=COLLECTION --location=LOCATION --searches-from-file=SEARCHES_FROM_FILE [[--rrf-weights=[WEIGHT,…] : --combine-output-data-fields=[DATA_OUTPUT_FIELD,…] --combine-output-metadata-fields=[METADATA_OUTPUT_FIELD,…] --combine-output-vector-fields=[VECTOR_OUTPUT_FIELD,…] --combine-top-k=COMBINE_TOP_K]] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
Batch search data objects from a Vector Search collection. Searches can be specified in a JSON file via --searches-from-file.
EXAMPLES
To batch search data objects from collection my-collection in location us-central1 using searches defined in searches.json, run: 
gcloud vector-search collections data-objects batch-search --collection=my-collection --location=us-central1 --searches-from-file=searches.json

Example searches.json: [

{
  "semanticSearch": {
    "searchText": "sci-fi movie",
    "searchField": "vector1",
    "topK": 10
  }
},
{
  "vectorSearch": {
    "searchField": "vector2",
    "topK": 5,
    "vector": { "values": [0.1, 0.2, 0.3] }
  }
}
 ]
REQUIRED FLAGS
--collection=COLLECTION
The collection to batch search data objects from.
--location=LOCATION
Location of the collection.
--searches-from-file=SEARCHES_FROM_FILE
Path to a JSON file containing a list of searches. Each element in list should be a JSON object representing a Search message, e.g., {"semanticSearch": {"searchText": "…", "searchField": "…"}}. Keys must be camelCase as in API definition. Example file content: [ { "vectorSearch": { "vector": { "values": [ 1, 2, 3, 4 ] }, "searchField": "genre_embedding", "topK": 10, "outputFields": { "dataFields": [ "director", "genre", "title", "year" ] } } }, { "semanticSearch": { "searchText": "sci-fi movie", "searchField": "plot_embedding", "taskType": "SEMANTIC_SIMILARITY", "topK": 10 } }, { "textSearch": { "searchText": "movie 1", "dataFieldNames": ["title"], "topK": 10 } } ]
OPTIONAL FLAGS
