Metadata filters are specified in the <metadataFilters/>
element in tika-config.xml
. They are run in order, and order matters.
See TikaServerEndpointsCompared for which endpoints apply metadataFilters in tika-server. They Metadata filters are applied in tika-pipes and tika-app when using the -J option. MetadataFilters are not applied when Tika streams output.
FieldNameMappingFilter
This is used to select fields to include and to rename fields from the Tika names to preferred names. This was initially designed for modifying field names before emitting document to OpenSearch or Solr.
...
If you need different behavior, implement a WriteFilterFactory
, add it to your classpath and specify it in the tika-config.xml
.

4. AutoDetectParserConfig

We've mentioned briefly above some of the factories that can be modified in the AutoDetectParserConfig
. There are other parameters that can be used to modify the behavior of the AutoDetectParser
via the tika-config.xml
the behavior of the AutoDetectParser
via the tika-config.xml
. The AutoDetectParser
is built from/contains the <parsers/>
element (or SPI if no <parsers/>
element is specified) in the tika-config
. Because of this, the configuration of the AutoDetectParser
differs from the component parsers that it wraps – the AutoDetectParser
uses its own <autoDetectParserConfig/>
element at the main level inside the <properties/>
element.
