ObjectDB Database Search

Hello ObjectDB Team I might have read the solution to this issue some times before, but I could not find an answer now. So sorry for bothering you. I want do add an @ Index annotation to a member of an existing Entity. This changes affects also existing databases. Is there any best practice

I would like to request support for case insensitive string indexes . Case-insensitive search is a very common requirement and adding a separate field for every indexed field is a pain. Regards, Natalia.   natmaclin Natalia Levine

It seems that the query is executed using a composite index on the  mapFromCli field. Could you please provide details on composite indexes that include that field? Unexpectedly, one of the values in that index is NULL rather than multiple values reflecting the indexed fields. This may indicate
