Solr Did you mean (Spell check component)

I use solr for my apps and i integrated the spellcheck component but i have some problems :

First : When i type a term separated by space they give me the correction for each term

Eg : "wat ters" => "what term" but the true is watters

Second : When i type some phrase with some wrong term. although the other terms are correct they apply the spell for all terms.

Eg : "Difreences in lankuage use conventions" => "Differences in language use conversions".

The true is "Differences in language use conventions"

This is my config in solrconfig.xml :

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
            <str name="queryAnalyzerFieldType">textSpell</str>
            <lst name="spellchecker">
                <str name="name">default</str>
                <str name="field">spell</str>
                <str name="spellcheckIndexDir">spellchecker</str>
            </lst>
</searchComponent>

<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
            <lst name="defaults">
                <str name="spellcheck.onlyMorePopular">true</str>
                <str name="spellcheck.extendedResults">false</str>
                <str name="spellcheck.count">1</str>
            </lst>
            <arr name="last-components">
                <str>spellcheck</str>
            </arr>
</requestHandler>

Schema.xml :

Field type:
