<searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
<str name="name">suggest</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str>
<!-- Alternatives to lookupImpl:
org.apache.solr.spelling.suggest.fst.FSTLookupFactory [finite state automaton]
org.apache.solr.spelling.suggest.fst.WFSTLookupFactory [weighted finite state automaton]
org.apache.solr.spelling.suggest.jaspell.JaspellLookupFactory [default, jaspell-based]
org.apache.solr.spelling.suggest.tst.TSTLookupFactory [ternary trees]
-->
<str name="field">AllContent</str> <!-- the indexed field to derive suggestions from -->
<float name="threshold">0.005</float>
<str name="buildOnCommit">true</str>
<!-- 使用自定义suggest词库词 -->
<str name="sourceLocation">suggest.txt</str>
<!-- <str name="spellcheckIndexDir">spellchecker</str> -->
</lst>
</searchComponent>
这里的suggest.txt词库默认应该是
utf-8 无BOM文档，否则solr读取有问题，
如果utf-8有BOM，那么词库第一行无法读取：
solr suggest 自定义词库和系统词库一起使用：
<!-- 可以定义多个，name查询spellchecker -->
<lst name="spellchecker">
<str name="name">suggestcustom</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str>
<str name="field">AllContent</str>
<float name="threshold">0.005</float>
<str name="buildOnCommit">true</str>
<!-- 使用自定义suggest词库词 -->
<str name="sourceLocation">suggest.txt</str>
<!-- <str name="spellcheckIndexDir">spellchecker</str> -->
</lst>
查询方式：http://localhost:8080/solr/resource/suggest?q=全&wt=json&indent=true&spellcheck=true&spellcheck.build=true&spellcheck.reload=true
&spellcheck.dictinotallow=suggest&spellcheck.dictinotallow=suggestcustom
