At the end of this page, you have a tested retriever on your knowledge base, promoted as the live default.
## Before you start
Before you start, sign in to the dashboard and select the organization you want to work in.
* You need a role that can manage resources to add, edit, or index retrievers.
* You need a knowledge base with at least one processed source. See [Create a knowledge base](/docs/guides/knowledge/create-a-knowledge-base).
## Configure and test
The tab lists existing retrievers and marks the live default **Default**.
Select **Add** on **Vector search** for most agents. Select **Customize** on **Custom retriever** for advanced options.
A toast confirms **Indexing started**. Wait for the progress bar to finish.
Enter a question an end user would ask, then select **Search**.
Check that the top chunks contain the answer. Try several real questions.
A toast confirms **Set as default retriever**. The card now shows the **Default** badge.
## The Test retriever dialog
The dialog is titled **Test retriever** and searches only the retriever you opened it from. Type a question into the **Enter a question…** field and press Enter or select **Search**.
Results appear under a **Top results** header. Each chunk shows its source document title, the rendered content, a rank marker such as **#1**, and a **Score** badge. For what the score means, see [Retrievers explained](/docs/guides/knowledge/retrievers-explained).
A line above the results tells you when the answering index was built. If the retriever needs a reindex, the line notes that later changes are not in the index yet and offers **Reindex**. Results clear on their own when the index changes.
| Message | When it appears |
| ------------------------------------------------------------ | ------------------------------------------------------------------- |
| **No results. Try a different question.** | The search ran but nothing matched. |
| **Search failed. Check the retriever status and try again.** | The search itself failed, often because the retriever is not ready. |
| **Untitled document** | The matched chunk's source has no title. |
## Verify
Run a test query against the promoted retriever. The **Top results** show the chunks your agent receives when it searches this knowledge base. The card carries the **Default** badge and no status badge.
## Reference
### The Retriever tab
Open a knowledge base and select the **Retriever** tab. The retriever marked **Default** answers live for your agent. A guide strip below the tab bar tracks three steps: **Add a retriever**, **Add test questions**, and **Run experiments**.
| State | What you see |
| -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| No retrievers | Title **How your agent finds answers** with an **Add a retriever** button. The preset picker opens once on its own if you can manage resources. |
| Retrievers exist | Heading **How your agent searches**, an **Add retriever** button, and one card per retriever. |
| No retriever indexed or indexing | A blue notice titled **Index a retriever to use it**. An unindexed retriever stays out of the agent's Knowledge tool and cannot be tested. |
| Stale retrievers | An amber alert, for example **1 retriever needs reindexing**, with a **Reindex all** button and a confirmation dialog. |
| Deleted retrievers exist | A **Recently deleted (N)** button that opens the restore dialog. A deleted retriever keeps its index for 30 days. |
### The Add a retriever picker
**Add retriever** opens a dialog titled **Add a retriever**. An info strip recommends starting with Vector Search. Four cards are available:
| Card | Description shown | Badge |
| -------------------------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------- |
| **Vector search** | "Solid all-round semantic search." | Strategy badge **Vector**. |
| **Keyword + vector blend** | "Mixes exact terms with meaning." | Strategy badge **Hybrid**. |
| **Keyword / exact terms** | "Best for codes, names, and exact phrases." | Strategy badge **Keyword**. |
| **Custom retriever** | "Configure search, embedding model and chunking yourself." | Badge **advanced**. Its **Customize** button opens the **Build from scratch** dialog. |
Each strategy badge carries a tooltip explaining the search style. An **Add** button on a preset card creates the retriever at once. The button reads **Added** and is disabled when a retriever with that strategy already exists. **Done** closes the dialog.
If the configuration already exists, no new retriever is created, and a toast names the existing one.
### The Build from scratch dialog
The dialog holds a **Name** field of up to 40 characters, then two sections. An info icon beside most fields explains what it controls.
For a new retriever, the **Name** field fills itself from the **Search** strategy and the **Embedding model**, for example `Vector · OpenAI · 3-small`. The strategy shows as `Vector`, `Hybrid`, or `Keyword`, and the model drops its `(default)` suffix.
The name follows those fields until you type your own name, which then stays. If the name is already used on this knowledge base, a suffix such as `(2)` is added. If you clear the field, the retriever gets the generated name.
| Section | Fields |
| ------------------------- | ---------------------------------------------------------------------- |
| **1 · How it's indexed** | **Index**, **Chunk size**, **Chunk overlap**, and **Embedding model**. |
| **2 · How it's searched** | **Query**, **Search**, **Refinement**, and **Results to retrieve**. |
Under the **Parent-child** index, the chunk fields read **Child chunk size** and **Child overlap**. An **Advanced chunking (parent size/overlap)** section then holds **Parent chunk size** and **Parent overlap**.
When **Refinement** is **Re-rank top results**, the first count field reads **Passages to re-rank**. A second field, **Results to retrieve**, sets how many re-ranked passages the agent gets.
Number fields accept whole numbers only. A value out of range shows its allowed range under the field, and **Add** stays disabled until you fix it.
| Field | Allowed values |
| -------------------------------------------------- | ------------------------------------------------------------------ |
| **Chunk size** and **Child chunk size** | 200 to 4000, or to the embedding model's limit when that is lower. |
| **Parent chunk size** | 200 to 4000. It cannot be smaller than the child chunk size. |
| **Chunk overlap** and **Parent overlap** | 0 up to a maximum that depends on the chunk size. |
| **Passages to re-rank** or **Results to retrieve** | 1 to 100. |
| **Results to retrieve** after re-ranking | 1 up to the number of passages to re-rank. |
### The retriever card
Each retriever renders as a card with its name, a summary line, and a footer.
| Element | Meaning |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Default** badge | This retriever is the live default for the knowledge base. |
| Summary line | The strategy in short form, for example "Vector", "Hybrid · Re-rank", or "Keyword · Parent-child". |
| Status badge | **Needs indexing** before the first build, or **Needs reindex** when documents changed. A ready retriever shows no status badge. |
| **Index A** badge | Shown when the knowledge base has several retrievers. Retrievers with the same letter share one index, and reindexing any of them rebuilds it for all. |
| **Auto** / **Manual** badge | The reindex mode. **Auto** reindexes after a scheduled crawl, though your own edits still need a manual reindex. **Manual** reindexes only when you start it. |
| **+ Index** button | Starts the first build, or a retry after an error. |
| **Reindex** button | Shown when the retriever is stale. Opens the **Apply pending changes** approval dialog. |
While a build runs, the card shows **Indexing** or **Replacing** with a percentage and a progress bar. A failed build shows a red **Indexing failed** alert with a **Details** popover and a **Retry** button.
When single documents fail to index, an amber alert reads **Repairing N documents**. They are temporarily unavailable. **Details** lists each document and its retry attempts. Tars retries on its own, and **Retry now** schedules another attempt at once. See [Manage documents](/docs/guides/knowledge/manage-documents) for the reindex flow.
### The card Actions menu
The menu on a card offers:
| Action | What it does |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------- |
| **View config** | Opens a read-only view of the configuration, grouped into **1 · How it's indexed**, **2 · How it searches**, and **Updates**. |
| **Edit config** | Opens the **Edit retriever** dialog. Hidden while the retriever is indexing or reindexing. |
| **Test retriever** | Opens the **Test retriever** dialog. Shown only when the retriever can serve queries. |
| **Make default** | Promotes this retriever to the live default. Shown when it is ready or stale and not already the default. |
| **Delete** | Moves the retriever to **Recently deleted** for 30 days. Shown to organization admins only. The last indexed retriever cannot be deleted. |
When a change in **Edit config** requires a rebuild, the footer warns that saving reindexes the retriever. A retriever with settings the form cannot show can only be renamed there.
