+# Clickzetta Vector Database Integration
+
+This module provides integration with Clickzetta Lakehouse as a vector database for Dify.
+
+## Features
+
+- **Vector Storage**: Store and retrieve high-dimensional vectors using Clickzetta's native VECTOR type
+- **Vector Search**: Efficient similarity search using HNSW algorithm
+- **Full-Text Search**: Leverage Clickzetta's inverted index for powerful text search capabilities
+- **Hybrid Search**: Combine vector similarity and full-text search for better results
+- **Multi-language Support**: Built-in support for Chinese, English, and Unicode text processing
+- **Scalable**: Leverage Clickzetta's distributed architecture for large-scale deployments
+
+## Configuration
+
+### Required Environment Variables
+
+All seven configuration parameters are required:
+
+```bash
+# Authentication
+CLICKZETTA_USERNAME=your_username
+CLICKZETTA_PASSWORD=your_password
+
+# Instance configuration
+CLICKZETTA_INSTANCE=your_instance_id
+CLICKZETTA_SERVICE=api.clickzetta.com
+CLICKZETTA_WORKSPACE=your_workspace
+CLICKZETTA_VCLUSTER=your_vcluster
+CLICKZETTA_SCHEMA=your_schema
+```
+
+### Optional Configuration
+
+```bash
+# Batch processing
+CLICKZETTA_BATCH_SIZE=100
+
+# Full-text search configuration
+CLICKZETTA_ENABLE_INVERTED_INDEX=true
+CLICKZETTA_ANALYZER_TYPE=chinese  # Options: keyword, english, chinese, unicode
+CLICKZETTA_ANALYZER_MODE=smart    # Options: max_word, smart
+
+# Vector search configuration
+CLICKZETTA_VECTOR_DISTANCE_FUNCTION=cosine_distance  # Options: l2_distance, cosine_distance
+```
+
+## Usage
+
+### 1. Set Clickzetta as the Vector Store
+
+In your Dify configuration, set:
+
+```bash
+VECTOR_STORE=clickzetta
+```
+
+### 2. Table Structure
+
+Clickzetta will automatically create tables with the following structure:
+
+```sql
+CREATE TABLE <collection_name> (
+    id STRING NOT NULL,
+    content STRING NOT NULL,
+    metadata JSON,
+    vector VECTOR(FLOAT, <dimension>) NOT NULL,
+    PRIMARY KEY (id)
+);
+
+-- Vector index for similarity search
+CREATE VECTOR INDEX idx_<collection_name>_vec
+ON TABLE <schema>.<collection_name>(vector) 
+PROPERTIES (
+    "distance.function" = "cosine_distance",
+    "scalar.type" = "f32"
+);
+
+-- Inverted index for full-text search (if enabled)
+CREATE INVERTED INDEX idx_<collection_name>_text
+ON <schema>.<collection_name>(content)
+PROPERTIES (
+    "analyzer" = "chinese",
+    "mode" = "smart"
+);
+```
+
+## Full-Text Search Capabilities
+
+Clickzetta supports advanced full-text search with multiple analyzers:
+
+### Analyzer Types
+
+1. **keyword**: No tokenization, treats the entire string as a single token
+   - Best for: Exact matching, IDs, codes
+
+2. **english**: Designed for English text
+   - Features: Recognizes ASCII letters and numbers, converts to lowercase
+   - Best for: English content
+
+3. **chinese**: Chinese text tokenizer
+   - Features: Recognizes Chinese and English characters, removes punctuation
+   - Best for: Chinese or mixed Chinese-English content
+
+4. **unicode**: Multi-language tokenizer based on Unicode
+   - Features: Recognizes text boundaries in multiple languages
+   - Best for: Multi-language content
+
+### Analyzer Modes
+
+- **max_word**: Fine-grained tokenization (more tokens)
+- **smart**: Intelligent tokenization (balanced)
+
+### Full-Text Search Functions
+
+- `MATCH_ALL(column, query)`: All terms must be present
+- `MATCH_ANY(column, query)`: At least one term must be present
+- `MATCH_PHRASE(column, query)`: Exact phrase matching
+- `MATCH_PHRASE_PREFIX(column, query)`: Phrase prefix matching
+- `MATCH_REGEXP(column, pattern)`: Regular expression matching
+
+## Performance Optimization
+
+### Vector Search
+
+1. **Adjust exploration factor** for accuracy vs speed trade-off:
+   ```sql
+   SET cz.vector.index.search.ef=64;
+   ```
+
+2. **Use appropriate distance functions**:
+   - `cosine_distance`: Best for normalized embeddings (e.g., from language models)
+   - `l2_distance`: Best for raw feature vectors
+
+### Full-Text Search
+
+1. **Choose the right analyzer**:
+   - Use `keyword` for exact matching
+   - Use language-specific analyzers for better tokenization
+
+2. **Combine with vector search**:
+   - Pre-filter with full-text search for better performance
+   - Use hybrid search for improved relevance
+
+## Troubleshooting
+
+### Connection Issues
+
+1. Verify all 7 required configuration parameters are set
+2. Check network connectivity to Clickzetta service
+3. Ensure the user has proper permissions on the schema
+
+### Search Performance
+
+1. Verify vector index exists:
+   ```sql
+   SHOW INDEX FROM <schema>.<table_name>;
+   ```
+
+2. Check if vector index is being used:
+   ```sql
+   EXPLAIN SELECT ... WHERE l2_distance(...) < threshold;
+   ```
+   Look for `vector_index_search_type` in the execution plan.
+
+### Full-Text Search Not Working
+
+1. Verify inverted index is created
+2. Check analyzer configuration matches your content language
+3. Use `TOKENIZE()` function to test tokenization:
+   ```sql
+   SELECT TOKENIZE('your text', map('analyzer', 'chinese', 'mode', 'smart'));
+   ```
+
+## Limitations
+
+1. Vector operations don't support `ORDER BY` or `GROUP BY` directly on vector columns
+2. Full-text search relevance scores are not provided by Clickzetta
+3. Inverted index creation may fail for very large existing tables (continue without error)
+4. Index naming constraints:
+   - Index names must be unique within a schema
+   - Only one vector index can be created per column
+   - The implementation uses timestamps to ensure unique index names
+5. A column can only have one vector index at a time

+# Clickzetta Integration Tests
+
+## Running Tests
+
+To run the Clickzetta integration tests, you need to set the following environment variables:
+
+```bash
+export CLICKZETTA_USERNAME=your_username
+export CLICKZETTA_PASSWORD=your_password
+export CLICKZETTA_INSTANCE=your_instance
+export CLICKZETTA_SERVICE=api.clickzetta.com
+export CLICKZETTA_WORKSPACE=your_workspace
+export CLICKZETTA_VCLUSTER=your_vcluster
+export CLICKZETTA_SCHEMA=dify
+```
+
+Then run the tests:
+
+```bash
+pytest api/tests/integration_tests/vdb/clickzetta/
+```
+
+## Security Note
+
+Never commit credentials to the repository. Always use environment variables or secure credential management systems.
