# Searching with tile mode

## Overview

Tile Mode search follows the same overall workflow as standard object detection search. See **Running Your First Search** for the full walkthrough of temporal extent, spatial extent, and running a search. The difference is how you select a seed image: instead of a free-form selection, Tile Mode uses a fixed-size search area you position directly on the ingested image.

## Selecting a Seed Image on the Ingest Screen

1. After selecting a file on the Ingest screen, select the **magnifying glass** icon on the map toolbar.
2. Choose a tile size: **128x128**, **256x256**, or **4096x4096**.

   A fourth option, free-form, is also available here but is used for standard object detection rather than Tile Mode. See **Running Your First Search** for that workflow.

3. A box of the selected size appears on the map. Drag it to position it over the area you want to use as your seed image.
4. Once positioned, choose **Save to My Images** to add it to your list of seed images, or **Cancel** to discard it.

{% hint style="info" %}
Saving a tile here does not automatically start a search. It adds the tile to your list of seed images, available the next time you search.
{% endhint %}

## Running the Search

1. Navigate to **Search** (magnifying glass icon in the left navigation).
2. Select your saved tile from the list of seed images.
3. Choose the matching tile Detector for the size you selected:
   * `Tile | 128px | 50% Overlap`
   * `Tile | 256px | 50% Overlap`
   * `Tile | 4096px | 50% Overlap`
4. Complete the rest of the search setup (temporal extent, spatial extent) as described in **Running Your First Search**, then run the search.

{% hint style="info" %}
Using a Detector size that doesn't match the seed image's tile size will affect match quality. Always pair a 128x128 seed image with the 128px Detector, and so on.
{% endhint %}

## Reading Results

Results display the same way as any other search. See **Reading Your Search Results** for the full walkthrough of the context map, closest matches, and adding results to a Taxonomy category.
