The same example config for the wiki also has entries for analyzing/fuzzy suggesters there is an example schema here: http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/core/src/test-files/solr/collection1/conf/schema-phrasesuggest.xml and with solrconfig here: http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/core/src/test-files/solr/collection1/conf/solrconfig-phrasesuggest.xml the "two" analyzers are confusing. the queryAnalyzerFieldType is just a solr thing for all suggester/spellcheckers and unrelated to analyzing suggester. so e.g. you'd make this type do minimal stuff if anything (set to keywordtokenizer, or something like that phrase_suggest that will try to parse out the field names and operators too but otherwise not do any tokenization or anything). the suggestAnalyzerFieldType is the one being passed to analyzing/fuzzy suggester as the analyzer.. fuzzy suggester is just like analyzing suggester, except it also corrects typos while autosuggesting.
