Thanks for enlightening, Shawn :) I thought DIH does parallel db request for all the entities defined in a document.
I do believe that DIH is easier to use that's why I am trying to find a way to use this in my current system. But as I explained above since I have so many sub entities,each returns list of response which will be joined in to parent. for more than 2 lacs document, full import is taking forever. What I am looking for is a way to speed up my full import using DIH only. To achieve this I tried to split the document in 2 and do full import parallely. but with this approach latest import overrides other document indexed data, since unique key(property_id) is same for both documents. One way I could think of is to keep document in different core which will maintain different index files and merge the search results from both cores while performing search on indexed data. But is this a good approach? -- View this message in context: http://lucene.472066.n3.nabble.com/Getting-error-while-excuting-full-import-tp4329153p4330704.html Sent from the Solr - User mailing list archive at Nabble.com.
