# Quick Search

Run Quick Search to find tiles like your labels, filter by confidence, refine with new labels, and label results fast with Quick Validation.

Quick Search finds the tiles in your project area that look most like your positive labels. It is fast, so you can run it often, check the results and improve your labels. For the full comparison with Deep Search, see [Quick Search or Deep Search](/improve-your-results/quick-vs-deep-search.md).

## Run a Quick Search

1. Add at least one positive label to the map. See [Label tiles](/search/label-tiles.md).
2. Open the **Quick Search** tab in the Labels card and select **Run Predictions**.

3. Wait a moment. The most similar tiles appear in the **Results** panel and on the map with a purple outline. Your own labels keep their blue (positive) and red (negative) outlines.

4. To change how many tiles come back, select **Config**, enter a number from 1 to 1,000, and select **Update**. The default is 500.

## Filter by confidence

The histogram under **Filter by Confidence** shows how sure Earth Index is about each match. Confidence is how closely a tile resembles your labelled tiles.

Drag the slider from **Low** towards **High** to hide the weaker matches. The count at the bottom of the panel, for example **499 Predictions**, drops as you move right. Use **High to Low** to change the sort order of the tile list.

## Update after new labels

Add positive or negative labels, whether from predicted tiles or from your own observations, then select **Update** in the Results panel. Earth Index searches again using all of your labels. Repeat this loop of a few new labels followed by an update. It is the fastest way to improve the results.

## Quick Validation

Quick Validation steps through about 50 predicted tiles one at a time, so you can label them without zooming to each one yourself.

1. Select **Quick Validation** at the bottom of the Results panel.

   ![The predictions results panel with the Quick Validation button in its footer.](https://182773137-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIQB2eToY1Iv2IH6cERjn%2Fuploads%2Fgit-blob-090bb6ad59f1d622c53375b64b1070ef5e4c1bbb%2Fpredictions-results.jpg?alt=media)
2. Earth Index zooms to the first unlabelled tile and opens the **Quick Validation** panel. Look closely at the tile.
3. Select **Positive** or **Negative** to label it. Select **Skip** if you cannot tell.

   ![Quick Validation panel with the positive, negative and skip buttons and the progress bar.](https://182773137-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIQB2eToY1Iv2IH6cERjn%2Fuploads%2Fgit-blob-f1acdeb9971b2f106202a4dd2bfc7d17a2687d89%2Fquick-validation.jpg?alt=media)
4. Repeat until the counter reaches zero. The counter reads **50 remaining** at the start.
5. To choose which tiles you see, use **Filter by**: **High Confidence**, **Medium Confidence** or **Low Confidence**. High shows the 50 strongest matches, Low shows the 50 weakest, and Medium shows 50 from the middle. The filter appears when there are more than 50 predictions.

When you finish, select **Update** in the Results panel to search again with your new labels. Marking wrong results as negative is the quickest way to collect negatives. See [Why negatives matter](/improve-your-results/why-negatives-matter.md).

## What to expect

* Quick Search does not train a model. It averages the numbers that describe your positive tiles and returns the nearest tiles in the project area. Negative labels push the search away from look-alikes. See [How Earth Index finds matches](/improve-your-results/how-search-works.md).
* Quick Search is limited per day. See [Limits and quotas](/reference/limits-and-quotas.md).
* **Run Predictions** is unavailable until you add one positive label. The panel says "Add at least one positive label to run quick search."
* If every prediction is already labelled, the panel says "All predictions have already been labeled. Add more labels to the map or increase the predictions config." Add labels or raise the number in **Config**.
