Request handle solrconfig.xml Spellchecker - solr

Question

I am trying to set up spellchecker, according to solr documentation. But when I am testing, I don't have any suggestion. My piece of code follows:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="classname">solr.IndexBasedSpellChecker</str>
<str name="name">default</str>
<str name="field">name</str>
<str name="spellcheckIndexDir">./spellchecker</str>
</lst>
<str name="queryAnalyzerFieldType">textSpell</str>
</searchComponent>
<requestHandler name="/spellcheck" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<!-- Optional, must match spell checker's name as defined above, defaults to "default" -->
<str name="spellcheck.dictionary">default</str>
<!-- omp = Only More Popular -->
<str name="spellcheck.onlyMorePopular">false</str>
<!-- exr = Extended Results -->
<str name="spellcheck.extendedResults">false</str>
<!-- The number of suggestions to return -->
<str name="spellcheck.count">1</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
The query I send to Solr:
q=%2B%28text%3A%28gasal%29%29&suggestField=contentOriginal&ontologySeed=gasal&spellcheck.build=true&spellcheck.q=gasal&spellcheck=true&spellcheck.collate=true&hl=true&hl.snippets=5&hl.fl=text&hl.fl=text&rows=12&start=0&qt=%2Fsuggestprobabilistic
Does anybody know why?? Thanks in advance

First, don't repeat queryAnalyzerFieldType twice in the component configuration.
It is recommended not to use a /spellcheck handler but instead to bind the spellcheck component to the standard query handler (or dismax if it is what you use) like this:
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<lst name="defaults">
...
</lst>
<arr name="last-components">
<str>spellcheck</str>
...
</arr>
</requestHandler>
You can then call it like this:
http://localhost:8983/solr/select?q=komputer&spellcheck=true
Also don't forget to build the spellcheck dictionary before you use it:
http://localhost:8983/solr/select/?q=*:*&spellcheck=true&spellcheck.build=true
You can force the dictionary to build at each commit by configuring it in the component:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="classname">solr.IndexBasedSpellChecker</str>
<str name="name">default</str>
<str name="field">name</str>
<str name="spellcheckIndexDir">./spellchecker1</str>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>
Finally, make sure that your name field is really an indexed field of type textSpell and that it contains enough content to build a good dictionary. In my case, I have a field named spellchecker that is populated from a couple of fields of my index (using copyField instructions in the schema).
