Question

我尝试使用SOLR 4.4的突出显示功能。经过一番尝试后，它终于有效了，但并不像我预期的那样：

Generell设置：我有一个文本和一个标题字段。两者都被索引和搜索，但只在标题字段中需要突出显示。

第一次尝试：文档的标题字段设置为string =＆gt;即使存储了字段，也没有突出显示结果
第二次尝试：将字段更改为text_ws（仅WhiteSpace-Tokenizer）。我不太确定我是否必须index标题字段，所以我做到了。 =＆GT; HL工作，但仅用于直接匹配（q = Apple在标题中没有HL Apple-Pie - q = Apple-Pie确实如此）
第3次尝试：将ngram添加到标题字段。现在q：apple给了一个热门，但突出了完整的Apple-pie，而不仅仅是查询词。

现在的问题是：是预期的行为还是只有一种方法可以突出显示查询词

我将令牌系统从WhiteSpaceTokenizerFactory更改为NGramTokenizerFactory并删除了NGramFilterFactory - ＆gt;现在它（几乎）按预期工作了
