schema.xml changes, need re-indexing ?

Hi,

 

We currently have a big index in production. We would like to add 2 non-required fields to our schema.xml :

 

<field name="myfield" type="boolean" indexed="true" stored="true" required="false"/>          

<field name="myotherfield" type="string" indexed="true" stored="true" required="false" multiValued="true"/>           

 

I made some tests:

 

-          I stopped tomcat

-          I changed the schema.xml

-          I started tomcat

 

The data was still there and I was able to add new document with theses 2 fields.

 

So far, it looks I won't need to re-index all my data. Am I right ? Do I need to re-index all my data or in that case I'm fine ?

 

Thank you !

You should be fine - no need to re-index your data.

Adding and removing fields is generally safe to do without a re-index. Changing a field (its type, analyzers, etc) requires more caution and generally does require a re-index.

I always run
http://localhost:8983/solr/admin/cores?action=RELOAD&core=corename in the
browser when I wanna reload solr and see any changes in config xmls.

I have not seen this mentioned anywhere, but I found a useful 'trick' to restart solr without having to restart tomcat. All you need to do is 'touch' the solr.xml in the solr.home directory. It can take a few seconds but solr will restart and reload any config.

Cheers

I believe you're fine with that. Don't need to reindex all solr database.
