How to disable Text Extraction in Apache Jackrabbit Oak

instructions.md

1. Find the location of the oak-lucene jar file:

   find crx-quickstart/launchpad/felix -name "bundle.info" -exec grep oak-lucene {} \; -print
   

   Example output:

   launchpad:resources/install.crx3/15/oak-lucene-1.2.2.jar
   crx-quickstart/launchpad/felix/bundle96/bundle.info
   

2. Take the second line of the output and remove bundle.info from the path, following the example above, we have:

   crx-quickstart/launchpad/felix/bundle96
   

3. cd to the subdirectory of that directory starting with "version" in the name:

   cd crx-quickstart/launchpad/felix/bundle96/version*
   

4. Extract the tika-config.xml file from that jar file to verify that you have the correct jar:

   jar -xvf bundle.jar org/apache/jackrabbit/oak/plugins/index/lucene/tika-config.xml
   

5. Check that the file was extracted:

   vi org/apache/jackrabbit/oak/plugins/index/lucene/tika-config.xml
   

6. Replace the contents of the file with the tika-config.xml file below.
7. Backup the bundle.jar file and update the jar file with the new version of the tika-config.xml:

   jar -uvf bundle.jar org/apache/jackrabbit/oak/plugins/index/lucene/tika-config.xml
