Searching

Performing Queries

• Single search queries are performed with the original _search endpoint by replacing the knn field with a gsi_knn field in the request body.

  note

  Remember to replace the vector field with your index's specific vector fields name.

• Batch queries are performed with a custom endpoint and request body.

Single search query example:

POST <serverHostName>:9200/<indexName>/_search

{
  "query": {
    "gsi_knn": {
      "field": "description_vector",
      "vector": [
        0.0015746655408293009,
        0.025234133005142212,
        0.0031481462065130472....
      ],
      "topk": 2,
      "prefilter": {
        "sub_category": "Dress",
        "source": "comsumer"
      },
      "filterOperator": "OR"
    }
  },
  "size": 30
} 

Batch of queries example:

POST <serverHostName>:9200/gsi/search/multiquery/<indexName>/<nameOfVectorField>

{
  "queries": [
    {
      "vector": [
        0.25973913073539734,
