My use case is to index 2 files: metadata file and a binary pdf file to a
unique solr id. Metadata file has content in form of xml file and schema
fields are mapped to elements in that file.
What I do: Extract content from pdf files(using pdftotext), process that
content and retrieve specific information(example: pdf's first page/line has
information about the medicine, research stage). Information
retrieved(medicine/research stage) needs to be indexed and one should be
able to search/sort/facet.
I can create a xml file with information retrieved(lets call this as
metadata file). Now assuming my schema would be
<field name="medicine" type="text" stored="true" indexed="true"/>
<field name="researchStage"...... ../>
Is there a way to put this metadata file and the pdf file in Solr?
What I have tried:
a) Based on a suggestion in archives, I zipped these files and gave to
ExtractRequestHandler. I was able
to put all the content in SOLR and make it searchable. But it appear as
content of zip file.
(i had to apply some patches to Solr Code base to make this work). But
this is not sufficient as the
content in metadata file is not mapped to field names.
curl
"http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true"; -F
"myfile=@file.zip"
b) I tried to work with DataImportHandler(binURLdatasource). But I dont
think I understand how it works.
So could not go far.
If someone has tips, please share.
I want to avoid creating 1 file(by merging pdf text + metadata file).
