We are working on an application that allows some users to add files (pdf, ms word, odt, etc), located on their local hard disk, to our internal system and allows other users to search for them. So we are considering Solr for the indexing and search functionalities of the system. Along with the file content, we want to index some metadata related to the file.
It seems obvious that Solr couldn't import the file from the local disk of the user, so the system will have to import the file into a directory that Solr can reach and instruct Solr to index the file with the metadata, but is it possible to index the file + metadata with a JSON/XML request? It seems that the only way to index a file with some metadata is to build a request that would look like the following exemple that uses curl. The developer would like to avoid using parameters in the url to pass arguments. curl " http://localhost:8080/solr/update/extract?literal.id=doc10&literal.name=BLAH&defaultField=text"; --data-binary @/path/to/file.pdf -H "Content-Type: application/pdf" Additionally, it seems that if a subsequent request is sent to the indexer to update the file, if the metadata are not passed to Solr with the request, they are deleted. Thanks for your help, Roland.
