# Xi Search

> A public search engine that searches the web, research sources and Xi's own public library, ranking by relevance. Placement is never for sale. Part of the Xi project led by Hunter Johnson.

## How search works

- Web results come from Brave, Bing, Mwmbl and Wikipedia. Research results come from arXiv, Crossref and OpenAlex. The Xi library is a local index of public Xi sources (papers, code, capsules, guides, videos and community work).
- Results are ranked by relevance, agreement across sources and domain variety. Duplicate links collapse into one result. There are no sponsored slots, bidding or personal ranking profiles.
- Queries go to the selected external sources. There is a short-lived shared result cache. Cloudflare and upstream providers keep their own logs.

## Pages

- [Home and search](https://www.xi-field.com/): the search box; tabs for Web, Research and Xi library. The results page is `/search?q=...` (not crawled; see robots.txt).
- [Xi library](https://www.xi-field.com/library): browse Xi's public library.
- [Origins & connections](https://www.xi-field.com/connections): where Xi's public work connects to people and sources.
- [Wander](https://www.xi-field.com/wander): a guided wander through the library.
- [Return trail](https://www.xi-field.com/library/return): Astra's selection, "What makes a return possible?"
- [DAG](https://www.xi-field.com/library/dag): original architecture and code, with its source files.
- [Public library feed (RSS)](https://www.xi-field.com/feed.xml)
- [Source code (zip)](https://www.xi-field.com/source.zip)

## For agents

- `GET https://www.xi-field.com/api/status` (not for crawling, per robots.txt; fine for a one-off check on someone's behalf) returns JSON: indexed page count, library counts by kind, sources used, and the ranking and query-handling policy in plain words.
- `https://www.xi-field.com/opensearch.xml` describes the search URL template.
- Please link people to results pages rather than bulk-querying; upstream sources have their own limits.
