Search Experience Review

# 前端实践
This note comes from a typical on-site search improvement task. The problem was not complicated, but the impact was obvious: users could technically find content, yet the experience still felt slow and inaccurate.
Symptoms
- The first search overlay open had a visible delay
- Result snippets were abrupt and keyword matches were hard to notice
- Entering two keywords reduced result count too aggressively
Approach
We did not add any extra service and kept the local search.xml flow. The optimization focused on only three things:
- Load the index file only when the search overlay is actually opened
- Show shorter snippets while typing to reduce cognitive load
- Highlight matched keywords to reduce the feeling that nothing was found
Acceptance Criteria
| Metric | Before | After |
|---|---|---|
| Time to first usable search | ~2.3s | ~1.2s |
| Result snippet length | Inconsistent | Around 100 characters |
| Common keyword hit rate | Fair | Stable |
Implementation Note
One detail mattered a lot: do not fetch the full search index during the initial homepage render. The difference is small on a tiny demo site, but it becomes obvious on a real content-heavy site.

Conclusion
Search does not get better just because it becomes more complex. On a static site like this, getting load timing, keyword highlighting, and snippet extraction right usually delivers a noticeable improvement on its own.
