XY-ish problem -- if you are deleting a bunch of documents by id, why have you switched from using delete-by-id to using delete-by-query? What drove that decision? Did you try using delete-by-query in your 3.6 setup?
: my f1 field is my key field. It is unique. ... : On my old solr 3.6, I don't use the same line to delete document, I use: : java -jar -Ddata=args -Dcommit=no post.jar : "<delete><id>113422</id></delete>" ... : why this method do not work now ? https://people.apache.org/~hossman/#xyproblem XY Problem Your question appears to be an "XY Problem" ... that is: you are dealing with "X", you are assuming "Y" will help you, and you are asking about "Y" without giving more details about the "X" so that we can understand the full issue. Perhaps the best solution doesn't involve "Y" at all? See Also: http://www.perlmonks.org/index.pl?node_id=542341 -Hoss http://www.lucidworks.com/
