SOLR Query result not showing new field

Question

I have added a new sort field in schema.xml, uploaded DIHConfigFile.xml and Schema.xml in SOLR config.

<field name="recommendationRank" type="string" indexed="true" stored="true" multiValued="false" required="false"/>

After this I did run zkcli, restarted SOLR and zookeeper both and also reindexing in solr.

Sorting based on the new field do give me the results back but i dont see the new field itself in the response. http://localhost:48100/solr/MainSystem1/select?indent=on&q=:&sort=recommendationRank_EN_US%20desc&wt=json

Update for query result

Answer 1

the field name shown is recommendationRank and in your query you have recommendationRank_EN_USas sort option . Is that a copy field ?

I suggest you do a simple query to see if the document is populated correctly with the new field value after reindexing your docs or not.

say recommendationRank:xyz (some value which you will know as per you indexing logic from the source system).

Can you share the output of the above query with debugQuery=on for further debugging.

Also, i would suggest you enable docValue for the fields which you are using or plan to use for sort/facet/pivot/stat/highlighting etc to avoid high field cache and improve the query performance.
