# Perform Retrieval Tests

You can evaluate how effectively your Enterprise Knowledge Garden (EKG) retrieves relevant information by using the Retrieval Testing tab. This feature allows you to simulate user queries and analyze the returned chunks for relevance and accuracy.

# How to Perform a Retrieval Test

From the main interface of your EKG, navigate to the Retrieval Testing tab.
In the search bar provided, enter the query you want to test and press Enter. The search function utilizes semantic understanding to find relevant information based on the meaning and context of a query.

# Analyzing the Results

The system will display a list of Retrieved Chunks that it considers relevant to your query. Each chunk is presented on a card, giving you the following information:

Content: A preview of the text within the chunk.
Similarity Score: A score (e.g., Similarity: 88) that indicates how closely the chunk's content matches your query. A higher score means a stronger match.
Management Options: You have the same options to edit or add Metadata as you do in the Chunk Viewer. Refer to editing and managing individual chunks for more details

# Refining Your Test

To refine the displayed chunks and test different retrieval scenarios, you can use the available options in the Retrieve Settings. For a detailed explanation of these concepts, please refer to the Core Concepts documentation.

Click the Options button (or an equivalent control) to open the refinement settings. From here, you can:

Adjust the Similarity Score: Control how closely a query must match the stored information.
Set the Top K: Define the initial number of content chunks retrieved for your query.
Enable the Reranker: When enabled, chunks are reordered for better relevance. You can also select a specific Rerank Model. (This is under progress, will be ready in sometime)
Define the Top N: Specify the number of chunks the reranker will display. (This is under progress, will be ready in sometime)
Filter by Metadata and Tags: Select specific metadata and tags to narrow down the results to only those chunks that are associated with them.

Click Apply to view the newly filtered chunks based on your selections.
