i receive the following error when trying to implement auto-complete based on edismax type.

solr config, use the following request handler with edismax type:
<requestHandler class="solr.SearchHandler" name="autocomplete" >
<lst name="defaults">
<str name="defType">edismax</str>
<str name="rows">10</str>
<str name="fl">*,score</str>
<str name="qf">locality_suggest locality_ng^5.0 locality_nge^10.0</str>
<str name="debugQuery">false</str>
</lst>
this error occurred only if query contains specific symbols like + – $ @ after word
