一、
随着互联网的快速发展，信息量的爆炸式增长，如何快速、准确地检索到所需信息成为了一个重要问题。搜索引擎优化（Search Engine Optimization，SEO）是提高网站在搜索引擎中排名的一系列策略。文本索引是搜索引擎优化的重要组成部分，它能够帮助搜索引擎快速定位到用户查询的关键词。本文将介绍如何使用Snobol4语言实现文本索引与搜索引擎优化。
二、Snobol4语言简介
Snobol4是一种高级编程语言，由David J. Farber和Ralph E. Griswold于1962年设计。它以其强大的文本处理能力而闻名，特别适合于文本处理和模式匹配【7】。Snobol4的语法简洁，易于理解，且具有丰富的文本处理函数。
三、Snobol4文本索引实现
1. 数据结构【8】设计
在Snobol4中，我们可以使用数组【9】来存储文本数据。每个数组元素可以存储一个单词或短语，数组索引可以表示单词或短语在文本中的位置。
2. 索引构建
以下是一个简单的Snobol4程序，用于构建文本索引：
```snobol
:INDEX
