推荐答案

你不需要做任何特别的事情.只需为您的发行版获取 Tesseract OCR 设置，然后在系统上安装.确保您的 PATH 变量具有 Tesseract 主目录的条目，并且设置了 TESSDATA_PREFIX 变量并指向 Tesseract 主目录.重新启动 Solr，您就可以开始了.当您通过 /update/extract 处理程序将文档推送到索引时，您应该能够看到 OCR 组件.

You don't need to do anything special. Simply get the Tesseract OCR setup for your distro and install it on the system. Make sure your PATH variable has an entry for the Tesseract home directory, and the TESSDATA_PREFIX variable is set and also points to the Tesseract home directory. Restart Solr and you're good to go. You should be able to see the OCR component when you push documents to the index through the /update/extract handler.

默认情况下，Tesseract 仅随英文模型一起提供.从此处获取其他语言的模型.

By default, Tesseract only ships with the English model. Get models for other languages from here.
