Summary

Document the Apache Tika 4.1.0 upgrade in the 15.10 tree (en, ja, zh-cn, de, ko, fr, es). Only the development tree */15.10/ is edited.

Describes the changes in codelibs/fess#3666 and codelibs/fess-crawler#225 (both merged).

Changes

  • install/upgrade.rst: new section "Upgrading from 15.9 to 15.10": tika.xml is no longer read, metadata name changes, tk: / X-TIKA: / zip: metadata removed, Tesseract and PDF properties files (timeoutMillis, removed PDFParserConfig properties), charset names, changes for plugin developers.
  • config/crawler-ocr.rst: tesseract / ImageMagick must be on the PATH of the crawler process; Tesseract timeout is timeoutMillis.
  • config/crawler-advanced.rst, config/admin-index-backup.rst: remove tika.xml references.
  • config/properties.rst: default of crawler.metadata.content.excludes now includes tk:.* (the generator's --check passes).

Notes

  • Merge order: fess-parent#92 -> fess-crawler#225 -> docker-fess#99 -> fess#3666 -> fess-docs (this PR).
  • OCR behavior with a real Tesseract was not verified, so the OCR page describes only what the code does.

Update the 15.10 documentation tree in all seven languages for the Tika 4
upgrade (codelibs/fess#3666, codelibs/fess-crawler#225).

- install/upgrade: add "Upgrading from 15.9 to 15.10" covering the retired
  tika.xml, metadata name changes, the removal of tk:/X-TIKA:/zip: metadata,
  Tesseract and PDF properties files, charset names and changes for plugin
  developers.
- config/crawler-ocr: tesseract and ImageMagick must be on the PATH of the
  crawler process; the Tesseract timeout property is timeoutMillis.
- config/crawler-advanced, config/admin-index-backup: drop tika.xml and
  describe the new behavior.
- config/properties: update the default of crawler.metadata.content.excludes.
