Search for documents by semantic similarity

Semantic search endpoint with batch processing capabilities

get

Initiate a search operation with a query text of up to 400 words and receive the most semantically similar responses from the stored knowledge. For question-answering, convert your question into an ideal answer and submit it to receive similar real answers.

Query parameters

Search Optimization Tips

For Question Answering

When searching for an answer to a question, try formulating your query as if it were an ideal answer. For example:

Instead of: "What is vector embedding?" Try: "Vector embedding is a technique that converts text into numerical vectors in a high-dimensional space."

For a deeper understanding of how vector embeddings work and why this search approach is effective, see What are Vector Embeddings and Vector Databases?

Adjusting Result Count

Start with n=3 for quick, high-relevance results
Increase to n=10 or higher for more comprehensive information
If search returns insufficient information, try increasing the n parameter

Time-Based Filtering

Use the from and to parameters to focus on documents from specific time periods:

Recent documents: Set from to a recent date
Historical analysis: Specify a specific date range
Excluding outdated information: Set an appropriate to date

Batch Operations

For efficiently handling large volumes of search queries, Rememberizer supports batch operations to optimize performance and reduce API call overhead.

Performance Considerations

When implementing batch operations, consider these best practices:

Optimal Batch Size: Start with batch sizes of 5-10 queries and adjust based on your application's performance characteristics.
Rate Limiting: Include delays between batches to prevent API throttling. A good starting point is 1 second between batches.
Error Handling: Implement robust error handling to manage failed requests within batches.
Resource Management: Monitor client-side resource usage, particularly with large batch sizes, to prevent excessive memory consumption.
Response Processing: Process batch results asynchronously when possible to improve user experience.

For high-volume applications, consider implementing a queue system to manage large numbers of search requests efficiently.

This endpoint provides powerful semantic search capabilities across your entire knowledge base. It uses vector embeddings to find content based on meaning rather than exact keyword matches.
