内存优先架构
</h3>
<p class="text-secondary leading-relaxed mb-4">
RediSearch作为Redis官方推出的强大模块，将Redis从高性能内存数据结构存储系统扩展为具备全文搜索、二级索引和复杂查询能力的搜索引擎<a href="#ref-201" class="citation text-blue-600 hover:bg-blue-50 px-1 rounded">[201]</a>。
</p>
<p class="text-secondary leading-relaxed">
基于倒排索引和内存存储的核心技术原理，RediSearch能够实现亚毫秒级的查询响应，特别适合对实时性要求极高的应用场景<a href="#ref-201" class="citation text-blue-600 hover:bg-blue-50 px-1 rounded">[201]</a>。

地理空间索引
</h3>
<p class="text-secondary leading-relaxed mb-4">
RediSearch提供两种专门的地理空间字段类型：<code class="bg-base-200 px-2 py-1 rounded text-sm">GEO</code>和<code class="bg-base-200 px-2 py-1 rounded text-sm">GEOSHAPE</code>
