Objects deleted-3DSpace/3DSpaceIndex

We had 3DSpace indexing issue last month and it is resolved now.
Some 3DSpace objects are deleted in the database and we wanted to validate if the missing objects are due to 3DSpace indexing issue.
We have not run the TCL script generated by mql>validate searchindex;
Is there any other possible ways the 3DSpaceindex deleting 3DSpace data/meta data ?
