Memories search (POST /v4/search) provides minimal-latency search optimized for real-time interactions. This endpoint prioritizes speed over extensive control, making it perfect for chatbots, Q&A systems, and any application where users expect immediate responses. 
import Supermemory from 'supermemory';

const client = new Supermemory({
  apiKey: process.env.SUPERMEMORY_API_KEY!
});

const results = await client.search.memories({
  q: "machine learning applications",
  limit: 5
});

console.log(results)
Sample Output: 
{
  "results": [
    {
      "id": "mem_ml_apps_2024",
      "memory": "Machine learning applications span numerous industries including healthcare (diagnostic imaging, drug discovery), finance (fraud detection, algorithmic trading), autonomous vehicles (computer vision, path planning), and natural language processing (chatbots, translation services).",
      "similarity": 0.92,
      "title": "Machine Learning Industry Applications",
      "type": "text",
      "metadata": {
        "topic": "machine-learning",
        "industry": "technology",
        "created": "2024-01-10"
      }
    },
    {
      "id": "mem_ml_healthcare",
      "memory": "In healthcare, machine learning enables early disease detection through medical imaging analysis, personalized treatment recommendations, and drug discovery acceleration by predicting molecular behavior.",
      "similarity": 0.89,

      "type": "text"
    }
  ],

}

​
Container Tag Filtering

Filter by user, project, or organization: 
const results = await client.search.memories({
  q: "project updates",
  containerTag: "user_123",  // Note: singular, not plural
  limit: 10
});

​
Threshold Control

Control result quality with similarity threshold: 
const results = await client.search.memories({
  q: "artificial intelligence research",
  threshold: 0.7,  // Higher = fewer, more similar results
  limit: 10
});

​
Reranking

Improve result quality with secondary ranking: 
const results = await client.search.memories({
  q: "quantum computing breakthrough",
  rerank: true,  // Better relevance, slight latency increase
  limit: 5
});

​
Query Rewriting

Improve search accuracy with automatic query expansion: 
const results = await client.search.memories({
  q: "How do neural networks learn?",
  rewriteQuery: true,  // +400ms latency but better results
  limit: 5
});

​
Include Related Content

Include documents, related memories, and summaries: 
const results = await client.search.memories({
  q: "machine learning trends",
  include: {
    documents: true,        // Include source documents
    relatedMemories: true,  // Include related memory entries
    summaries: true         // Include memory summaries
  },
  limit: 5
});

​
Metadata Filtering

Simple metadata filtering for Memories search: 
const results = await client.search.memories({
  q: "research findings",
  filters: {
    AND: [
      { key: "category", value: "science", negate: false },
      { key: "status", value: "published", negate: false }
    ]
  },
  limit: 10
});

​
Chatbot Example

Optimal configuration for conversational AI: 
// Optimized for chatbot responses
const results = await client.search.memories({
  q: userMessage,
  containerTag: userId,
  threshold: 0.6,     // Balanced relevance
  rerank: false,      // Skip for speed
  rewriteQuery: false, // Skip for speed
  limit: 3            // Few, relevant results
});

// Quick response for chat
const context = results.results
  .map(r => r.memory)
  .join('\n\n');

Complete Memories Search Example

Combining features for comprehensive results: 
const results = await client.search.memories({
  q: "machine learning model performance",
  containerTag: "research_team",
  filters: {
    AND: [
      { key: "topic", value: "ai", negate: false }
    ]
  },
  threshold: 0.7,
  rerank: true,
  rewriteQuery: false, // Skip for speed
  include: {
    documents: true,
    relatedMemories: false,
    summaries: true
  },
  limit: 5
});
