title: Advanced Retrieval
|
|
---
|
|
|
|
Mem0's **Advanced Retrieval** feature delivers superior search results by leveraging state-of-the-art search algorithms. Beyond the default search functionality, Mem0 offers the following advanced retrieval modes:
|
|
|
|
1. **Keyword Search**
|
|
|
|
This mode emphasizes keywords within the query, returning memories that contain the most relevant keywords alongside those from the default search. By default, this parameter is set to `false`. Enabling it enhances search recall, though it may slightly impact precision.
|
|
|
|
```python
|
|
client.search(query, keyword_search=True, user_id='alex')
|
|
```
|
|
|
|
2. **Reranking**
|
|
|
|
Reranking allows you to reorder the memories returned by the default search based on relevance. This parameter is set to `false` by default. When enabled, it reorders the memories based on the relevance score.
|
|
|
|
```python
|
|
client.search(query, rerank=True, user_id='alex')
|
|
```
|
|
|
|
3. **Filtering**
|
|
|
|
Filtering enables you to narrow down the search results by applying specific criteria. This parameter is set to `false` by default. Activating it enhances search precision, potentially reducing recall by a small margin.
|
|
|
|
```python
|
|
client.search(query, filter_memories=True, user_id='alex')
|
|
```
|
|
|
|
**Note:** You can enable or disable these search modes by passing the respective parameters to the `search` method. There is no required sequence for these modes, and any combination can be used based on your needs.

### Latency Numbers
|
|
|
|
Here are the typical latency ranges for each search mode:
|
|
|
|
| **Mode** | **Latency** |
|
|
|---------------------|------------------|
|
|
| **Keyword Search** | **<10ms** |
|
|
| **Reranking** | **150-200ms** |
|
|
| **Filtering** | **200-300ms** |
