I am doing a POC to index pdf and word documents using solr search engine. I tried to search about detailed level information or articles but did not get\found any detailed article to do it. What I found is to use some solr package provided example. That is not I require.
Current information I have is one can use Solr Cell and Apache Tika to index pdf documents.
From some stakeoverflow I found link http://wiki.apache.org/solr/ExtractingRequestHandler but it is not tutorial or having steps to do what I want. Also, I want to call solr from .net application using solrnet.
I am using Solr 5.1 version.
I am providing sample code that I ran from solr reference document as below
bin/solr -e techproducts
It started example solr instance with techproducts core. After that I ran below command to index pdf document.
curl "http://localhost:8983/solr/techproducts/update/extract?literal.id=doc1&commit=true" -F "myfile=@example/exampledocs/solr-word.pdf"
It worked perfectly.
After that I have created new core from tomcat hosted solr server and on that I tried to run the same curl command and receiver error. I have added below request handler code in solrconfig.xml
<requestHandler name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
<str name="lowernames">true</str>
<str name="uprefix">ignored_</str>
<!-- capture link hrefs but ignore div attributes -->
<str name="captureAttr">true</str>
<str name="fmap.a">links</str>
<str name="fmap.div">ignored_</str>
</lst>
</requestHandler>
Script:
C:\tomcat-solr>curl "http://localhost:8090/solr/Core3/update/extract?literal.id=
doc1&commit=true" -F "myfile=@example/exampledocs/solr-word.pdf"
