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 ( + id STRING NOT NULL, + content STRING NOT NULL, + metadata JSON, + vector VECTOR(FLOAT, ) NOT NULL, + PRIMARY KEY (id) +); + +-- Vector index for similarity search +CREATE VECTOR INDEX idx__vec +ON TABLE .(vector) +PROPERTIES ( + "distance.function" = "cosine_distance", + "scalar.type" = "f32" +); + +-- Inverted index for full-text search (if enabled) +CREATE INVERTED INDEX idx__text +ON .(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 .; + ``` + +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.
