Description

I have an error with SpellCheckComponent since I have added this SearchComponent to /select RequestHandler (see solrconfig.xml).

<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">titre</str>

<!-- h4k1m: configure spellcheck if enabled -->
<str name="spellcheck">on</str>
<str name="spellcheck.dictionary">default</str>
<str name="spellcheck.extendedResults">true</str>
<str name="spellcheck.count">3</str>
<str name="spellcheck.alternativeTermCount">3</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">1</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="combineWords">false</str>
</lst>

The error seems to be related to range queries, with the [.. to ..] written in lowercase. The query performed by the SpellCheck component using 'to' in lower case throws the RANGE_GOOP error.
