12.0.0 - Upgrade Issues

  • Due to the standardisation of many [query processor options](../../../more/extra/padre_query_processor_options.md the format of some CGI parameters has been changed, and must be updated in any external systems setting CGI values. See Query processor options (collection.cfg) for full details.
  • The Redis service included with Funnelback 11.x may not shut down correctly during upgrades. Please ensure you shut down Funnelback manually before upgrading and check that the redis-server process is stopped.
  • Funnelback 11.x and greater embed a 64-bit Java virtual machine (JVM). If you are upgrading from an older version of Funnelback you may need to increase the max_heap_size by 50% to account for the increased memory requirements of the 64-bit architecture.
  • Some components of Funnelback now depend on the installation of freetype and fontconfig on the local system. On RedHat/CentOS systems, these may be installed with yum install freetype fontconfig if they are not present.
  • The <@IncludeUrl /> Modern UI tag is now part of the fb namespace: <@fb.IncludeUrl />. Form files must be updated accordingly.
  • The default filter for PDF to HTML conversion is now Tika (previously pdf2html). This might slightly affect the rendering of converted PDF files.
  • The -cjkt query processor option is no longer required and no longer supported.
  • The truncation operator (*) is no longer supported in queries unless the -service_volume=low query processor option is used.

12.0.0 - Selected improvements and bugfixes

  • Standardised the syntax of many query processor option settings.
  • Improved query completion performance.
  • Suppress duplicate descriptions in query completions.
  • Ability to bias result ranking based on gscope settings.
  • Funnelback shell tool for manual manipulation of stored content.
  • Services for remotely performing storage and mediator operations on Funnelback servers.
  • The Modern UIData Model rawInputParameters and inputParameterMap are now backed by the same Map: Any change made in one will be visible in the other. Existing hook scripts and FreeMarker template shouldn't be affected but some code simplification might be possible when parameters were injected into those Maps. Additionally, the additionalParameters map now takes arrays of Strings as values, as opposite to just Strings previously.
  • padre-sw may now be accessed directly at /s/padre-sw.cgi for debugging purposes.
  • Support for selectable metadata values.
  • Ability to turn off stemming of particular words when stemming is on by default.
  • More accurate reporting of filetypes.
  • Facet counts are now supported (through estimation) in DAAT mode.
  • Support many more complex query types in DAAT mode.
  • Support for anchor-text processing and redirect/duplicate information in push collections.
  • Ability to restart gathering from a checkpoint in Filecopy and TRIM collections.
  • Support for individual server authentication details via site profiles.
  • Fixed redis server security so manual security configuration is no longer required.
  • Improved URL status collection tool for web collections.
  • Added ability to snapshot push collection indexes so they can be distributed to remote servers safely.
  • Improved Funnelback uninstaller to remove environment settings.
  • Funnelback now includes a full Java development environment (rather than just the runtime environment) to provide better performance monitoring tools.
  • Fixed incorrect spelling in continuous updating configuration parameter names.
  • Fixed restarting of push collections after a service restart.
  • Improved logging for jetty web applications.
