Is a reindex required when changing a field to large=true?

[Walter Underwood <wu...@wunderwood.org>]

We are looking at changing a field property to be large=true. Can we do that without reindexing?

Also, I’d appreciate pointers to discussions about the performance implications.

To correct a misconception:

the collecion, apply the schema change and charge again the collection to
apply the changes.

No, you only need to reindex if your schema modifications cause a change in
the index on disk, just as Shawn wrote. If you have separate analyzers for
query- and index-time, do not reindex is you make changes to the query-time
analyzer.

Hi by my experience any change to the schema collection require delete the collecion, apply the schema change and charge again the collection to apply the changes.

Kind regards

I did not know what that option was, had to look it up.

That would not affect the index on disk in any way, so I do not believe
a reindex is required.

Thanks,

I did not know what that option was, had to look it up.

That would not affect the index on disk in any way, so I do not believe 
a reindex is required.
