Re: Would changing the schema version from 1.5 to 1.6 require a reindex

[Paras Lehana]

Hi Karl,

Maybe someone else could help if reindexing is needed if we upgrade Schema
version. However, I guess, useDocValuesAsStored only impacts the query side
assuming docValues had already been stored during indexing. It's actually
easier to try querying the fields after enabling this parameter and see if
that works without reindexing!

Would changing the schema version from 1.5 to 1.6 require a reindex

[Karl Stoney]

Hey,
I’m going to bump our schema version from 1.5 to 1.6 to get the implicit 
useDocValuesAsStored=true, would this require a reindex?

Thanks
Karl

it really depends on the change.

gneral rule of thumb is "yes" but there are lots of exceptions depending 
on what you're doing and how concerned you are about consistency -- 
adding fields/fieldTypes really doesn't require reindexing unless you have 
a default value.  removing "required" or going from single valued to 
multivalued (ie: relaxing rules) doesn't require reindexing. changing 
analyzers ... oy.  that's a big ball of wax.

if you really know what you are doing, and fully understand what's 
changing under the covers, there are lots of cases where you don't need to 
reindex ... but it's not recommended in general.

If you're using that field within the DIH .. then of course yes, but
normally/otherwise: No :)

At least, you have to reload the Core-Config .. don't know exactly how
that works while using Tomcat -- with the packaged Jetty, it's just
hitting /admin/cores (while in Multicore-Mode) or restarting the
Java-Process (in Singlecore-Mode)

Afaik, the document are just not affected from searching and therefore
missing in/excluded from the result.

Re: Changing the schema

[Chamnap Chhorn]

I wonder what if I add new field in the schema, do i have to reindex?

If no need to reindex, can i just update the schema.xml directly? After
that, Should I restart the tomcat service?

If no need to reindex, how about the existing documents? If I do a query
with new field, does it cause errors?

Brian,

Yes, you do need to reindex.  We've used Hadoop with Solr to speed up indexing 
by orders of magnitude for some of our customers.  Something to consider.

Changing the schema

[Brian Lamb]

If I change the field type in my schema, do I need to rebuild the entire
index? I'm at a point now where it takes over a day to do a full import due
to the sheer size of my application and I would prefer not having to reindex
just because I want to make a change somewhere.

Thanks,

Brian Lamb

changing the schema

[Lutz Steinborn]

Hi,

I'm using Solr now for a while and I'm feeling fine. Its much easier to use
as native Lucene.
Many thanks for the good job.

But one question cames up as the index goes bigger and bigger: is it
possible to add fields to the schema without a complete   reindex ?

We are using Solr for a b2b catalog application with millions of records. A
complete reindex takes hours.
