pagefind-net

A pure .NET library that generates Pagefind-compatible search indexes. No native binaries, no subprocess, no platform restrictions.

pagefind-net reimplements the Pagefind indexer in managed .NET code. It produces the same pagefind/ directory structure that the stock Pagefind JS/WASM query runtime consumes.

Packages

Pagefind.Net: The indexer. Accepts documents as PagefindRecord instances and writes pagefind-entry.json, .pf_meta, .pf_index, and .pf_fragment files.
Pagefind.Net.Frontend: Ships the Pagefind browser runtime (pagefind.js + wasm.en.pagefind). An MSBuild target auto-extracts the files into your project on build.

Features

Pure managed .NET - no native Rust binary, no Node.js dependency
AOT-compatible and trimming-safe
Zero-allocation tokeniser and stemmer hot paths
Produces indexes byte-compatible with Pagefind 1.5.2
MSBuild integration for automatic frontend extraction
Programmatic ExtractToAsync API for the JS/WASM runtime
Supports weighted segments for heading boosting and sub-page anchors

Getting started

		using Pagefind.Net;

var index = new PagefindIndex(new PagefindIndexOptions { Language = "en" });

index.AddRecord(new PagefindRecord
{
    Url = "/guide/",
    Title = "Getting started",
    Content = plainTextBody,
    WeightedSegments =
    [
        new WeightedSegment(h1Text, Weight: 7),
        new WeightedSegment(bodyText, Weight: 1),
    ],
});

await index.WriteAsync("wwwroot");
