Hi Jason
Thanks for the response.
You are right that re-indexing is required after making any changes to
Schema even i am re-indexing the docs in which i have
changed the fieldtypes, but here Emir is talking about full re-indexing
i.e. deleting the existing/core and creating new one that is
time consuming i think. My doubt is that i am not able to change the type
which has implementation classes like LongPointField/IntPointField to the
type with implementation classes LongPointField/IntPointField.t
But i am able to change into Text related fields like TextFields
and from TextFields to any other Int/Long type fields.
So i just want to know that what is exact dependency on these classes so
that iam able to change types of some fields ?
Thanks
Shubham
