Re: Deleting a field in schema.xml, reindex needed?

[Erick Erickson]

“Throws an error” is not very informative. _What_ error?

In general reindexing should not be required. This is often a result of trying 
to _use_ the field for something. Take a careful look at the error, that may 
give a clue.

Best,
Erick

Hi - Did you find any solution for this. Because am also facing the same
problem. After removing the field, it throws an error while doing full
index. And also the index gets failed.

Deleting a field won't require a reindex, but any data in that field
will remain in your index until you do.  This probably can affect the
performance of the index, but unless you're running with insufficient
resources, you may not even notice.

Thanks,
Shawn

When I have done this, it is in multiple steps.

1. Change the indexing so that no data is going to that field.
2. Reindex, so the field is empty.
3. Remove the field from the schema.

RE: Deleting a field in schema.xml, reindex needed?

[Markus Jelsma]

Hi - We did this on one occasion and Solr started complaining in the logs about 
a field that is present but not defined. We thought the problem would go away 
within 30 days - the time within every document is reindexed or deleted - but 
it did not, for some reason. Forcing a merge did not solve the warnings, 
although i thought it should.

So we decided to delete everything, reindex in a standby index and get that one 
back online. But don't worry, it are just warnings, everything worked well and 
nothing failed. Maybe our 30 days reindexing strategy failed at that point, or 
i didn't wait the for exactly 30 days.

Markus
