Search

A hand-rolled client-side index over every page on Codex Numerica — titles, section headers, and section excerpts. The whole index loads in your browser; nothing is sent anywhere.

About

How this search works

The index is a static JavaScript file (search-index.js) generated from every published HTML page on the site. For each page it stores the title, the meta description, and for each numbered section the section heading and the first paragraph of that section. The current index covers … pages and … sections.

The search itself is a small case-insensitive scorer that splits the query into terms and, for each indexed section, sums the number of term occurrences in the section’s title (weight ×3), heading (weight ×2), and excerpt (weight ×1). The 25 highest-scoring sections are returned, with matched terms highlighted.

There is no server, no tracking, no analytics. The index loads once when this page opens; everything after that is local.

For a more structured number-by-number lookup (with cross-cultural attestations grouped by evidence grade), use the Number Lookup tool.
