+# OceanBaseVectorSearchTool
+
+## Description
+
+This tool is designed for performing vector similarity searches within an OceanBase database. OceanBase is a distributed relational database developed by Ant Group that supports native vector indexing and search capabilities using HNSW (Hierarchical Navigable Small World) algorithm.
+
+Use this tool to find semantically similar documents to a given query by leveraging OceanBase's vector search functionality.
+
+For more information about OceanBase vector capabilities, see:
+https://en.oceanbase.com/docs/common-oceanbase-database-10000000001976351
+
+## Installation
+
+Install the crewai_tools package with OceanBase support by executing the following command in your terminal:
+
+```shell
+pip install crewai-tools[oceanbase]
+```
+
+or
+
+```shell
+uv add crewai-tools --extra oceanbase
+```
+
+## Example
+
+### Basic Usage
+
+```python
+from crewai_tools import OceanBaseVectorSearchTool
+
+tool = OceanBaseVectorSearchTool(
+    connection_uri="127.0.0.1:2881",
+    user="root@test",
+    password="",
+    db_name="test",
+    table_name="documents",
+)
+```
+
+### With Custom Configuration
+
+```python
+from crewai_tools import OceanBaseVectorSearchConfig, OceanBaseVectorSearchTool
+
+query_config = OceanBaseVectorSearchConfig(
+    limit=10,
+    distance_func="cosine",
+    distance_threshold=0.5,
+)
+
+tool = OceanBaseVectorSearchTool(
+    connection_uri="127.0.0.1:2881",
+    user="root@test",
+    password="your_password",
+    db_name="my_database",
+    table_name="my_documents",
+    vector_column_name="embedding",
+    text_column_name="content",
+    metadata_column_name="metadata",
+    query_config=query_config,
+    embedding_model="text-embedding-3-large",
+    dimensions=3072,
+)
+```
+
+### Adding the Tool to an Agent
+
+```python
+from crewai import Agent
+from crewai_tools import OceanBaseVectorSearchTool
+
+tool = OceanBaseVectorSearchTool(
+    connection_uri="127.0.0.1:2881",
+    user="root@test",
+    db_name="test",
+    table_name="documents",
+)
+
+rag_agent = Agent(
+    name="rag_agent",
+    role="You are a helpful assistant that can answer questions using the OceanBaseVectorSearchTool.",
+    goal="Answer user questions by searching relevant documents",
+    backstory="You have access to a knowledge base stored in OceanBase",
+    llm="gpt-4o-mini",
+    tools=[tool],
+)
+```
+
+### Preloading Documents
+
+```python
+from crewai_tools import OceanBaseVectorSearchTool
+import os
+
+tool = OceanBaseVectorSearchTool(
+    connection_uri="127.0.0.1:2881",
+    user="root@test",
+    db_name="test",
+    table_name="documents",
+)
+
+texts = []
+metadatas = []
+for filename in os.listdir("knowledge"):
+    with open(os.path.join("knowledge", filename), "r") as f:
+        texts.append(f.read())
+        metadatas.append({"source": filename})
+
+tool.add_texts(texts, metadatas=metadatas)
+```
