Are you using apache tika parser to parse pdf files? 1) Solr support parent-child block join using which you can index more than one file data within document object(if that is what you are looking for) https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-BlockJoinQueryParsers
2) If the unique key of the document that exists in index is equal to new document that you are reindexing, it will be overwritten. If you'd like to do partial updates via curl, here are some examples listed : http://yonik.com/solr/atomic-updates/ On Thu, Mar 24, 2016 at 3:43 AM, Jay Parashar <bparas...@slb.com> wrote: > Hi, > > I have couple of questions regarding indexing files (say pdf). > > 1) Is there any way to index more than one file to one document with > a unique id? > > One way I think is to do a “extractOnly” of all the documents and then > index that extract separately.
