Hi,

Looking at the source, it doesn't seem like fts-solr checks for settings changes using fts_index_have_compatible_settings() like fts-lucene does.

Is there any special reason for why fts-solr shouldn't also rebuild indexes if settings has changed?

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.
