Actually, a regular repair (with the Reset option unchecked) should also restore a deleted Quick Search item. Apparently something in the original database is preventing that from working. You can try running these statements with SQLite.exe (see
http://www.kinook.com/Forum/showthre...?threadid=2825):
INSERT INTO Item(ItemID,ItemTitle,TemplateItemID,StatusID,Icon ID,System,CreateDate,UpdateDate,AccessDate,Keyword Count,TitleAttributeID,ChildCount,LinkCount,Access Count,BlobSize,UncompressedSize) VALUES (990,'Quick Search',8,NULL,980,1,38197,38197,NULL,2,5,NULL,NUL L,NULL,NULL,NULL);
INSERT INTO ItemLink(ItemLinkID,ItemID,ParentItemID,Expanded,C hildPosition,DeleteDate,DeletedParentItemID) VALUES (984,990,996,0,0,NULL,NULL);
If that doesn't help, you'll probably need to restore a backup from before the problem occurred.
