Fix broken search on /articles/ (and other list pages)

[HeyItsGilbert]

Problem

The search box on /articles/ (and any list page with the same template) did nothing when you typed in it.

Root cause

The client-side filter in themes/powershell-community/layouts/_default/list.html throws a TypeError on the first card and aborts:

• Cards only get a data-tags attribute when the article has tags:

  {{ if .Params.tags }}data-tags="..."{{ end }}
  

• No articles use tags (they use categories/authors), so data-tags is never rendered.
• The search JS unconditionally calls .includes() on it:

  const tags = item.dataset.tags;   // undefined
  ... || tags.includes(searchTerm)  // TypeError: Cannot read properties of undefined

• The error throws inside the forEach on the first card, so the handler aborts and nothing filters.

Fix

Default the dataset reads to empty strings so a missing attribute no longer crashes the filter:

const title = item.dataset.title || '';
const content = item.dataset.content || '';
const tags = item.dataset.tags || '';

Known remaining limitation (not addressed here)

The filter only loops over .content-item elements currently in the DOM, which is just the paginated page (pagerSize: 10). So search only matches within the current page, not across all articles. Fixing that properly would require a real client-side index (e.g. Fuse.js + a generated JSON index) or server-side search — happy to follow up if wanted.

This only works if all the pages are rendered. Will look into a more comprehensive solution.
