Search Filter

A Chrome extension that applies include/exclude filters to searches on Google, Bing, and DuckDuckGo by rewriting the search query.

Primarily designed for image search to exclude results from stock-photo sites and AI-generated content.

Features

• Include and exclude filters for search queries
• Automatic domain detection: example.com → site:example.com
• Filter Groups to organize and toggle sets of filters
• Theme selection: Auto, Light, Dark
• Comes with some preset filter groups
• Action icon shows if filter is enabled/disabled

Supported Sites

• google.com
• bing.com
• duckduckgo.com

Installation (Unpacked)

1. Clone or download this repository.
2. Open chrome://extensions/ in chromium based browser.
3. Enable Developer mode.
4. Click Load unpacked and select the project folder.

Usage

1. Click the toolbar icon to open the popup.
2. Toggle on/off (top left in popup) to control whether queries are rewritten.
3. Use the Include or Exclude tab to manage filters.
4. Create Groups to organize related filters and toggle them on/off.
5. Add parameters:
   • Terms/Phrases: e.g., vintage, "19th century"
   • Domains: e.g., example.com (auto-converted to site: or -site:)

Run a search on a supported site; the extension updates the q parameter based on your active groups.

Behavior

• Adds parameters to your search query
• Detects domain inputs and converts them to site: or -site: filters
• Removes conflicting +/-/site: fragments in the typed query before applying filters to avoid duplicates
• Parameters like old photo are automatically formatted as "old photo"

Limitations

• Auto theme detection only works when opening extension popup
• Using too many filter parameters is not recommended (too long query)

Privacy

• No network requests are sent when searching, it just appends the selected filters to your search query
• All settings are stored locally in the browser
• Font for the extension popup is loaded from fonts.google.com
