我在尝试基于 edismax 类型实现自动完成时收到以下错误。

架构类型：

        <analyzer type="index">

    <!-- autocomplete_ngram : Matches any word in the input field, with implicit right truncation.
         This means that the field "A brown fox" will be matched by query "bro".

架构字段

        <!-- AutoComplete fields
         Construct documents containing these fields for all suggestions you like to provide
         Then use a dismax query to search on some fields, display some fields and boost others
     -->
    <field name="locality_id" type="int" indexed="true" stored="true" required="true"/>
    <!-- The main text to return as the suggestion. This is not searched -->
    <field name="locality_suggest" type="text_suggest" indexed="true" stored="true" omitNorms="true" multiValued="true" />

    <!-- A variant of textsuggest which only matches from the very left edge -->
    <copyField source="locality_suggest" dest="locality_nge"/>
    <field name="locality_nge" type="autocomplete_edge" indexed="true" stored="false" multiValued="true" />

    <!-- A variant of textsuggest which matches from the left edge of all terms (implicit truncation) -->
    <copyField source="locality_suggest" dest="locality_ng"/>
    <field name="locality_ng" type="autocomplete_ngram" indexed="true" stored="false" omitNorms="true" omitTermFreqAndPositions="true" multiValued="true" />

solr 配置，使用以下带有 edismax 类型的请求处理程序：

  <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>

仅当查询在单词后包含特定符号（如 + - $ @）时才会发生此错误
