I am trying to use Solr(5)s suggestion. Suggestion works but i am getting recurring suggestions.I tried to use grouping on suggestion, it does not work.How can i prevent recurring suggestions?
Here is necessary parts of my schema.xml:
<field name="Name" type="suggest" indexed="true" stored="true" multiValued="false"/> ...<fieldType name="suggest" class="solr.TextField"><analyzer type="index"> <tokenizer class="solr.StandardTokenizerFactory" /><filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.NGramFilterFactory" minGramSize="2" maxGramSize="15"/> </analyzer><analyzer type="query"><tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer></fieldType>My solrconfig.xml:
<searchComponent name="suggest" class="solr.SuggestComponent"><lst name="suggester"><str name="name">mySuggester</str> <str name="lookupImpl">AnalyzingInfixLookupFactory</str><str name="suggestAnalyzerFieldType">suggest</str> <str name="exactMatchFirst">true</str><str name="dictionaryImpl">DocumentDictionaryFactory</str> <str name="field">Name</str><str name="weightField">Price</str> <str name="buildOnCommit">true</str> <str name="buildOnStartup">false</str><str name="preserveSep">false</str> </lst> <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy"><lst name="defaults"> <str name="suggest">true</str><str name="suggest.count">5</str><str name="suggest.dictionary">mySuggester</str><str name="suggest.collate">true</str> </lst><arr name="components"><str>suggest</str><str>query</str> </arr>Example output for "acer" suggestions with params

Also grouping does not work :
suggest?&suggest.dictionary=mySuggester&suggest.q=acer&group=true&group.field=Name
