fix(search): preserve word boundaries between block elements - #3861
Conversation
The MDC parser drops newline-only text nodes between block siblings, so extractTextFromAst concatenated table cells, list items, blockquote paragraphs and nested component content without whitespace, making words at the start of those blocks unsearchable in the FTS index. Insert a single space when crossing a block boundary, only when neither side already provides whitespace, so inline text is preserved exactly. Fixes nuxt#3860

In `@src/runtime/internal/search.ts`:
- Line 195: Add common structural block tags such as article and figure to
BLOCK_TAGS so adjacent elements create text boundaries; add a regression test
confirming a search for “second” finds the second article when both are inside a
div.
- Around line 223-224: Update the ignored-tag check in the search traversal to
record whether the ignored node is a block before returning; determine its block
status before the early return and preserve the existing boundary behavior for
other nodes. Add coverage for direct text before and after an ignored block
within the same parent, verifying that searching for the trailing text finds its
section.

- Around line 195-198: Add `img` and `ruby` to the `INLINE_TAGS` set used by
`extractTextFromAst`, so reachable elements of either type do not create text
boundaries. Add AST-level regression tests confirming text remains joined across
both elements.

❓ Type of change
📚 Description
The MDC parser drops newline-only text nodes between block siblings (
@nuxtjs/mdccompiler), andextractTextFromAstjoined children with''. As a result, text from sibling block elements nested inside a top-level node was concatenated without whitespace:Words at the start of a table cell (
Description,api_key,Your,Request…) were therefore not matched byuseSearchCollection/queryCollectionSearchSections. The same happened for list items, paragraphs in blockquotes and loose list items, nested MDC components/slots and raw<br>.Fix:
extractTextFromAstnow inserts a single space when crossing a block-level boundary (tables, lists,p,pre,blockquote, headings,div,section,br,hr), and only when neither side already has whitespace.foo**bar**baz, punctuation after inline code/links/emphasis, and CJK text are unchanged. A naivejoin(' ')would break these.table > tbody > tr > td > p) never produce repeated whitespace.Tests
generateSearchSections: tables (hast and minimark bodies), lists (nested/loose), blockquotes, nested MDC components and slots,<br>/<hr>, nested block boundaries, ignored tags, plus inline-preservation cases for content and heading titles.searchCollection: end-to-end test parsing the issue's markdown with the MDC parser, indexing it into a real SQLite FTS5 table, and querying the first word of table cells.📝 Checklist
