Solr How to sorting suggestions by sales - solr

Question

We are trying to use solr on our website as a search engine , but we have a problem , we can not sort the suggestions by the number of sales.
I tried the components Facet, Terms, FreeTextLookupFactory and the spellcheck component, but in none of the above components are able to get the results that I want.
The most important thing that I would understand its if we can sort the suggestion for a weight chosen by us.
The version of solr we are using is the 5.0.
schema.xml:
<field name="name_complete" type="text_shingle" indexed="true" stored="true" required="false" multiValued="false" omitTermFreqAndPositions="true"/>
<fieldType name="text_shingle" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ShingleFilterFactory" maxShingleSize="4" outputUnigrams="true"/>
</analyzer>
</fieldType>
solrconfig.xml
FreeTextLookupFactory:
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">suggest_product_free</str>
<str name="lookupImpl">FreeTextLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">name_complete</str>
<str name="indexPath">suggest_product_free</str>
<str name="weightField">n_sales</str>
<str name="buildOnCommit">true</str>
<str name="suggestFreeTextAnalyzerFieldType">text_shingle</str>
<int name="ngrams">3</int>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="indent">true</str>
<str name="suggest">true</str>
<str name="suggest.count">10</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
spellcheck:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<lst name="spellchecker">
<str name="queryAnalyzerFieldType">text_shingle</str>
<str name="name">autocomplete</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.fst.WFSTLookupFactory</str>
<str name="field">name_complete</str>
<str name="buildOnCommit">true</str>
<float name="threshold">0.005</float>
<str name="spellcheckIndexDir">./suggester_autocomplete</str>
</lst>
</searchComponent>
<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<!-- Solr will use suggestions from both the 'default' spellchecker
and from the 'wordbreak' spellchecker and combine them.
collations (re-written queries) can include a combination of
corrections from both spellcheckers -->
<str name="spellcheck">true</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.onlyMorePopular">true</str>
<str name="spellcheck.dictionary">autocomplete</str>
<!--str name="spellcheck.dictionary">wordbreak</str>
<str name="spellcheck.extendedResults">true</str>
<str name="spellcheck.alternativeTermCount">5</str>
<str name="spellcheck.maxResultsForSuggest">5</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.collateExtendedResults">true</str>
<str name="spellcheck.maxCollationTries">10</str>
<str name="spellcheck.maxCollations">5</str-->
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
any ideas how I can make to order the suggestion for the weight?
Thanks to all and have a nice day.
example:
assume that I have these saved values on solr:
1: Reflex canon eos 7d (weight: 1)
2: Reflex canon eos 6d (weight: 2)
3: Reflex canon eos 70d (weight: 3)
and requested the string 'can'.
the result that I want:
canon eos
canon eos 70d
canon eos 6d
canon eos 7d
in practice would that it were a autocomplete that I can order for the weight.
