I guess that there is no setting for the fts-solr plugin that would be
require rebuilding to take place. If you change any fts-solr settings
(except for the url) I would expect the result in solr, providing there
were no errors, will be the same with or without a rebuild.

For fts-lucene there are settings which would change what is stored in
lucene. The relevant settings which are taken into account for lucene
index rebuild are in  fts_lucene_settings_checksum(): default_language,
whitespace_chars, normalize and no_snowball.
