Issue with Solr Suggester

I am trying to implement Suggester in SOLR 5.0,

Below is my configuration :-
<searchComponent name="suggest" class="solr.SuggestComponent">
        <lst name="suggester">
      <str name="name">my-suggester</str>
      <str name="lookupImpl">FuzzyLookupFactory</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="field">name</str>
      <str name="weightField">cityname</str>
      <str name="payloadField">id</str>
      <str name="suggestAnalyzerFieldType">text_general</str>
      <str name="buildOnStartup">true</str>
      </lst>
  </searchComponent>

  <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
    <lst name="defaults">
      <str name="suggest">true</str>
      <str name="suggest.count">10</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
  </requestHandler>


In Schema.xml :-
 <field name="name" type="text_general" indexed="true" stored="true"/>

 <fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" />
        <filter class="solr.LowerCaseFilterFactory"/>
       </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" />
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
        <filter class="solr.LowerCaseFilterFactory"/>
       </analyzer>
    </fieldType>

My data is like :-

Delhi
New Delhi
The New Castle



When I Query using following parameter below :-
http://localhost/solr/location/suggest?suggest.dictionary=my-suggester&suggest=true&suggest.build=true&suggest.q=Delhi

I get "Delhi" only in result but the ideal result is both Delhi and New
Delhi.


It will be very helpful if you guyz suggest me how to achieve this.

This is working as expected but the problem I get with wrong spelling
searches.

When I give suggest.q=Bhopml Fuzzy lookup suggests bhopal which is correct
buy in AnalyzingInfixSuggester it doesn't provide this .

I'm pretty sure that FuzzyLookup only goes from the beginning of the
field, so this is not surprising. To get what you're looking for you
probably would get more joy from the AnalyzingInfixSuggester.

Best,
