# QuickPeep
Small-scale 'artisanal web' search engine project, favouring quality over completeness.
## Motivation
Modern web search can be rubbish.
It feels like I'm getting the same websites time and time again, and that I rarely manage to come across small, independent websites instead of content/SEO mills.
Typical modern websites are rubbish. They bother you with adverts, annoying nagging pop-ups (often loaded with dark patterns), privacy-disregarding trackers and slow-loading content that relies on needless amounts of JavaScript to display plain rich text that has been possible with pure HTML for decades.
QuickPeep aims to index good-quality websites, favouring small personal sites (such as blogs), whilst cutting out the rubbish.
Websites that don't care about the reader's experience are not welcome; QuickPeep will detect pop-up nags, adverts and privacy issues in order to keep them away.
As a separate issue, many websites decide to use CloudFlare to intercept their traffic.
This is not in the spirit of the decentralised web; CloudFlare becomes a single party that, if compromised or dishonest, could exert a disproportional amount of power over users.
One notable example of this is that they bombard privacy-seeking users on VPNs or Tor with needless CAPTCHAs, giving them a worse experience on a lot of the web.
These websites will be detected so that they can be filtered out at will.
QuickPeep will follow the trade-off of preferring not to provide any results rather than to provide results laced with rubbish.
If you need to fall back to a conventional search engine, this will eventually be possible to do right within QuickPeep...
## Features
*Crossed-out things are aspirational and not yet implemented.*
- ~~Shareable 'rakepacks', so that anyone can run their own search instance without needing to rake (crawl) themselves~~
- ~~Dense encoding to minimise disk space usage; compressed with Zstd?~~
- Raking (crawling) support for
- HTML (including redirecting to Canonical URLs)
- ~~Language detection~~
- Redirects
- ~~Gemtext over Gemini~~
- RSS, Atom and JSON feeds
- XML Sitemaps
- Detection of anti-features, with ability to block or downrate as desired:
- CloudFlare
- Adverts
- Nagging pop-ups
- Trackers
- Article content extraction, to provide more weight to words found within the article content (based on a Rust version of Mozilla's *Readability* engine)
- (Misc)
- ~~Use of the Public Suffix List~~
- ~~Tagging URL patterns; e.g. to mark documentation as 'old'.~~
- ~~Page duplicate content detection (e.g. to detect `/` and `/index.html`, or non-HTTPS and HTTPS, or non-`www` and `www`...)~~
- ~~Language detection for pages that don't have that metadata available.~~
## Limitations
- Only supports English (and English dialects) for now.
- Should hopefully be customisable later on, but even though I can speak some foreign languages, I don't know any communities to start with to seed non-English search.
- Websites have to be manually allowed and tagged.
- It's otherwise difficult to know how to detect good-quality sites automatically, or to tag what they are.
- There may be ways to improve this; e.g. with machine learning techniques or crowdsourcing of data.
- The search index needs to remain small enough to be usable on modest hardware, so there's no way we can hope to index everything.

### Helper scripts
`scripts` contains some helper scripts, which you probably need to run before operating QuickPeep:
- `get_cf_ips.sh`: fetches IP addresses ued for CloudFlare detection.
- `get_adblock_filters.sh`: fetches adblock filters used to detect nags/adverts/trackers.
