Description

Attempting to spellcheck some long query terms can trigger org.apache.lucene.util.automaton.TooComplexToDeterminizeException. This change (previously discussed in SOLR-13190) adds a maxQueryLength option to DirectSpellchecker so that Lucene can be configured to not attempt to spellcheck terms over a specified length.
