fix(command-bar): reserve exact search action - #51
Merged
Conversation
📝 WalkthroughWalkthroughThe Command Bar now ignores blank input, filters visible suggestions, reserves an exact Search action for non-blank queries, preserves Ask AI ordering, and uses filtered matches for selection and navigation. Browser tests and feature documentation cover the updated behavior. ChangesCommand Bar suggestion behavior
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The command bar may still send Enter through a non-default search match instead of the reserved default search action, which can navigate users through the wrong provider; this correctness issue should be fixed before merge.

is exact only when its destination URL corresponds to the default search
provider for search_terms, preventing a first-ranked non-default provider from
becoming the automatic Search action. Ensure the synthesized default Search
occupies the automatic-selection position while non-default search matches
remain non-default actions, and add a browser test confirming Enter still
navigates with the default provider when a non-default match is ranked first.

阻止非默认搜索匹配成为自动选择的 Search 操作
增强建议模式会自动选择索引 0，并将该匹配直接传给 NavigateToMatch()。即使 IsExactSearchMatch() 比较 GetSearchUrl(search_terms)，排在首位的非默认搜索匹配仍会被 Enter 选中。
仅当 URL 匹配默认搜索提供商时，才将匹配视为精确 Search。将合成的默认 Search 放入自动选择位置，并将非默认搜索匹配保留为非默认操作。添加浏览器测试，验证首位非默认搜索匹配不会改变 Enter 的默认提供商导航。

Please check back later.
Background
The command bar could hide the exact search action when other suggestions filled the visible five-row list. Empty or whitespace-only input could also keep stale suggestions visible.
Changes
Testing
Patch adds browser tests for reserved exact search actions, duplicate prevention, URL-like input, Ask AI row ordering, default search provider navigation, and empty or whitespace-only input suggestion clearing.
