# TRUEREF-0016 — Web UI: Search Explorer

## Overview
|
||||
|
||||
An interactive search interface within the web UI that lets users test the documentation retrieval system directly from the browser. Mirrors the two-step context7 flow: first resolve a library ID, then query documentation. Results are displayed with syntax highlighting. Useful for validating indexing quality and demonstrating the system to stakeholders.

|
||||
## Acceptance Criteria
|
||||
|
||||
- [ ] Search page at `/search` with two-step workflow
|
||||
- [ ] Step 1: Library name input → displays matching libraries with IDs and scores
|
||||
- [ ] Step 2: Click library → query input → displays ranked snippets
|
||||
- [ ] Syntax-highlighted code blocks (using a lightweight highlighter)
|
||||
- [ ] Snippet type badge (code vs info)
|
||||
- [ ] Breadcrumb display per snippet
|
||||
- [ ] Token count per snippet and total
|
||||
- [ ] "Copy as Markdown" button for the full response
|
||||
- [ ] Library switcher (return to step 1 without full page reload)
|
||||
- [ ] URL reflects current state (`/search?lib=/facebook/react&q=useState`)
|
||||
- [ ] No server-side rendering needed for this page (can be client-side)

## Search Page Logic
|
||||
|
||||
```svelte
|
||||
<!-- src/routes/search/+page.svelte -->
|
||||
<script lang="ts">
|
||||
import { page } from '$app/stores';
|
||||
import { goto } from '$app/navigation';
|
||||
|
||||
let libraryName = $state('');
|
||||
let selectedLibraryId = $state<string | null>(null);
|
||||
let query = $state('');
|
||||
let libraryResults = $state<LibrarySearchResult[]>([]);
|
||||
let snippets = $state<Snippet[]>([]);
|
||||
let loadingLibraries = $state(false);
|
||||
let loadingSnippets = $state(false);
|
||||
|
||||
async function searchLibraries() {
|
||||
loadingLibraries = true;
|
||||
const res = await fetch(
|
||||
`/api/v1/libs/search?libraryName=${encodeURIComponent(libraryName)}&query=${encodeURIComponent(query)}`
|
||||
);
|
||||
const data = await res.json();
|
||||
libraryResults = data.results;
|
||||
loadingLibraries = false;
|
||||
}
|
||||
|
||||
async function searchDocs() {
|
||||
if (!selectedLibraryId) return;
|
||||
loadingSnippets = true;
|
||||
const url = new URL('/api/v1/context', window.location.origin);
|
||||
url.searchParams.set('libraryId', selectedLibraryId);
|
||||
url.searchParams.set('query', query);
|
||||
const res = await fetch(url);
|
||||
const data = await res.json();
|
||||
snippets = data.snippets;
|
||||
loadingSnippets = false;
|
||||
|
||||
// Update URL
|
||||
goto(`/search?lib=${encodeURIComponent(selectedLibraryId)}&q=${encodeURIComponent(query)}`, {
|
||||
replaceState: true,
|
||||
keepFocus: true,
|
||||
});
|
||||
}
|
||||
</script>
|

```

||||
## Syntax Highlighting
|
||||
|
||||
Use a minimal, zero-dependency approach for v1 — wrap code blocks in `<pre><code>` with a CSS-based theme. Optionally integrate `highlight.js` (lightweight) as an enhancement:
|
||||
|
||||
```typescript
|
||||
// Optional: lazy-load highlight.js only when code snippets are present
|
||||
async function highlightCode(code: string, language: string): Promise<string> {
|
||||
const hljs = await import('highlight.js/lib/core');
|
||||
// Register only needed languages
|
||||
return hljs.highlight(code, { language }).value;
|
||||
}
|
||||
```
