If you add ShingleFilterFactory to you fieldType definition of tags field, you can obtain multi-word (shingle) suggestions. E.g. 'Car Radio' for 'Car R'. http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.ShingleFilterFactory I don't know how data is stored in keywords-field column. One line comma separated values? However you may need to change your tokenizer since 'Radio C' will return 'Radio Car' in this scenario.
