# OpenSearch Vector Search Edition

Use the ha3engine SDK to push documents and execute HA/SQL searches. This skill focuses on API/SDK usage only (no console steps).

Prerequisites

python3 -m venv .venv
. .venv/bin/activate
python -m pip install alibabacloud-ha3engine

- `OPENSEARCH_ENDPOINT` (API domain)

- `OPENSEARCH_INSTANCE_ID`

- `OPENSEARCH_USERNAME`

- `OPENSEARCH_PASSWORD`

- `OPENSEARCH_DATASOURCE` (data source name)

- `OPENSEARCH_PK_FIELD` (primary key field name)

Quickstart (push + search)

import os
from alibabacloud_ha3engine import models, client
from Tea.exceptions import TeaException, RetryError

cfg = models.Config(
    endpoint=os.getenv("OPENSEARCH_ENDPOINT"),
    instance_id=os.getenv("OPENSEARCH_INSTANCE_ID"),
    protocol="http",
    access_user_name=os.getenv("OPENSEARCH_USERNAME"),
    access_pass_word=os.getenv("OPENSEARCH_PASSWORD"),
)
ha3 = client.Client(cfg)

def push_docs():
    data_source = os.getenv("OPENSEARCH_DATASOURCE")
    pk_field = os.getenv("OPENSEARCH_PK_FIELD", "id")

    documents = [
        {"fields": {"id": 1, "title": "hello", "content": "world"}, "cmd": "add"},
        {"fields": {"id": 2, "title": "faq", "content": "vector search"}, "cmd": "add"},
    ]
    req = models.PushDocumentsRequestModel({}, documents)
    return ha3.push_documents(data_source, pk_field, req)


def search_ha():
    # HA query example. Replace cluster/table names as needed.
    query_str = (
        "config=hit:5,format:json,qrs_chain:search"
        "&&query=title:hello"
        "&&cluster=general"
    )
    ha_query = models.SearchQuery(query=query_str)
    req = models.SearchRequestModel({}, ha_query)
    return ha3.search(req)

try:
    print(push_docs().body)
    print(search_ha())
except (TeaException, RetryError) as e:
    print(e)

Script quickstart

python skills/ai/search/alicloud-ai-search-opensearch/scripts/quickstart.py

Environment variables:

Optional args: `--cluster`, `--hit`, `--query`.

SQL-style search

from alibabacloud_ha3engine import models

sql = "select * from <indexTableName>&&kvpair=trace:INFO;formatType:json"
sql_query = models.SearchQuery(sql=sql)
req = models.SearchRequestModel({}, sql_query)
resp = ha3.search(req)
print(resp)

Notes for Claude Code/Codex

Error handling

Validation

mkdir -p output/alicloud-ai-search-opensearch
for f in skills/ai/search/alicloud-ai-search-opensearch/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/alicloud-ai-search-opensearch/validate.txt

Pass criteria: command exits 0 and `output/alicloud-ai-search-opensearch/validate.txt` is generated.

Output And Evidence

Workflow

1) Confirm user intent, region, identifiers, and whether the operation is read-only or mutating.

2) Run one minimal read-only query first to verify connectivity and permissions.

3) Execute the target operation with explicit parameters and bounded scope.

4) Verify results and save output/evidence files.
