: 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.
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. -Hoss
