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
- Install SDK (recommended in a venv to avoid PEP 668 limits):
python3 -m venv .venv
. .venv/bin/activate
python -m pip install alibabacloud-ha3engine
- Provide connection config via environment variables:
OPENSEARCH_ENDPOINT(API domain)OPENSEARCH_INSTANCE_IDOPENSEARCH_USERNAMEOPENSEARCH_PASSWORDOPENSEARCH_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:
OPENSEARCH_ENDPOINTOPENSEARCH_INSTANCE_IDOPENSEARCH_USERNAMEOPENSEARCH_PASSWORDOPENSEARCH_DATASOURCEOPENSEARCH_PK_FIELD(optional, defaultid)OPENSEARCH_CLUSTER(optional, defaultgeneral)
Optional args: --cluster, --hit, --query.
SQL-style search
from alibabacloud_ha3engine import models
sql = "select * from &&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
- Use
push_documentsfor add/delete updates. - Large query strings (>30KB) should use the RESTful search API.
- HA queries are fast and flexible for vector + keyword retrieval; SQL is helpful for structured data.
Error handling
- Auth errors: verify username/password and instance access.
- 4xx on push: check schema fields and
pk_fieldalignment. - 5xx: retry with backoff.
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
- Save artifacts, command outputs, and API response summaries under
output/alicloud-ai-search-opensearch/. - Include key parameters (region/resource id/time range) in evidence files for reproducibility.
Workflow
- Confirm user intent, region, identifiers, and whether the operation is read-only or mutating.
- Run one minimal read-only query first to verify connectivity and permissions.
- Execute the target operation with explicit parameters and bounded scope.
- Verify results and save output/evidence files.
