I am looking for following solution in C#, Please provide sample code if possible:-
1. Delete all the index using delete query. 2. Take backup of all the old index, before regenerate. 3. Try to write unlike query for a field to delete stale index. 4. How can use transaction under index generation (delete all old index and generate index), so that if any error occurs than it will not affect old indexes. ryantxu wrote: > > escher2k wrote: >> I am trying to remove documents from my index using "delete by query". >> However when I did this, the deleted >> items seem to remain.
