Agnes,

Maybe Vlad's solution is better, do not know

but this works, have tested it

before the requery() , delete the tags, requery(), recreate tag

best with only one index
&& requery
&& save tag info
delete tag all
=requery()
&& recreate the one and only index if necessary
&& does not take too much additional time compared to the requery
index on field2 tag field2

begin transaction && works
