Question

您好，我是Solr的新手，但荧光笔有问题。荧光笔不会为每个匹配项都返回一个突出显示的文本，它在大多数情况下都有效，但在所有情况下都不能（请参见示例第二个条目）。有人可以帮我吗？

Solr版本：7.4.0

查询：

http://localhost:8983/solr/mpdv/select?hl.fl=mpdv_content_de&hl=on&q=mpdv_content_de:%22Dynamisches%20Anwendungsverhalten%22

结果：

  "highlighting":{
"y:\\MPDVAll\\ProductDocumentations\\de\\Procedures\\MDS_MOC\\MDS-Extensibility.pdf":{
  "mpdv_content_de":[" <em>Dynamisches</em> <em>Anwendungsverhalten</em>  \n\n• Spezifische Logik zur Sichtbarkeit/Aktivierbarkeit"]},
"y:\\MPDVAll\\ProductDocumentations\\de\\FunctionPackages\\MDS-BAS_8.1\\MDS-BAS_81.pdf":{}}}

Debugoutput：

在查询中使用hl.maxAnalyzedChars以获得突出显示的文本。您可以增加maxAnalyzedChars的值。

hl.maxAnalyzedChars：查找突出显示的字符数限制，之后将不突出显示。由于这是最慢的偏移量，因此对于基于分析的偏移量源来说，这主要只是性能问题。默认值为51200。
