🔑 增強重點摘要
- •The June 2026 update for Windows 11 is part of Microsoft's broader 'commitment to Windows quality' initiative, announced in March 2026, which aims to enhance search to find 'what matters faster' by surfacing apps, files, and settings more clearly.
- •Alongside the two-character query support, a 'Search by Substring' improvement is also rolling out, enabling users to discover files with compound names (e.g., 'MeetingNotesApril') by typing only a part of the name like 'April' or 'status', addressing a long-standing user frustration.
- •This search enhancement is included in the larger June 2026 Windows 11 update (KB5094126), which also features other significant performance improvements, such as a 'Low Latency Profile' designed to accelerate app launches and core shell experiences like the Start menu and Search itself.
- •Microsoft is actively developing an option to allow users to disable web search results within Windows 11's search function, a response to persistent user complaints about clutter and the forced promotion of Bing.

🛠️ 技術深入
- Windows Search is implemented as a Windows service, with the core component being the Indexer.
- The Indexer continuously crawls the file system and monitors file system notifications to maintain an up-to-date index of data.
- The search index is stored in an Extensible Storage Engine (ESE) file named
Windows.edb, typically located in\ProgramData\Microsoft\Search\Data\Applications\Windows\. - It utilizes 'iFilters' to extract textual content from various file formats (e.g., documents, audio, video) and 'property handlers' to derive metadata like file names and tags.
- The indexing process occurs in three main stages: queuing URLs (identifying items to be indexed), crawling URLs (accessing items and collecting data), and updating the index with the collected data.
- Windows Search supports incremental searches and uses the Advanced Query Syntax for complex queries.
- The system maintains two types of indices: value indices for filtering and sorting by entire property values, and inverted indices for quick word matching within textual content.
- For security and isolation, the search service typically runs two host processes: one in the system security context and another in the user security context.
🔮 前景展望AI analysis grounded in cited sources
User satisfaction with Windows Search will significantly increase.
The combination of two-character queries, substring search, and the upcoming option to disable web results directly addresses long-standing user frustrations, making local file discovery more intuitive and less cluttered.
Microsoft's focus on refining core Windows experience improvements will continue.
This update, alongside other performance enhancements like the Low Latency Profile, indicates a strategic shift towards refining fundamental OS functionalities based on user feedback, rather than solely pushing new AI features.
