I have followed the apache solr offical documentation but made changes to solr-config.xml according to them still have the same issue.

Answer 1

After reading your question and if I am not wrong, you are posting PDF file (which contains some text and images) to solr. The solr will only index that document it will not extract the images and store them to other location.
Solr internally uses Tika libraries for parsing the documents, but it cannot be used in your requirement
To achieve your requirement,
parse your pdf and extract all the images and other contents and store them
index all the extracted contents and pdf in solr.
