Sitecore Max Lucene Query Clause Count
Xing Liu • 4/14/2016
If you have encountered this following error:
It’s probably because your lucene query exceeded the max clause count setting. You can adjust this setting from the Lucene default config file:
The default max count is 4096 in Sitecore 8.1. You can adjust it based on your query size.
<setting name="ContentSearch.LuceneQueryClauseCount" value="4096" />
However, be cautious about using this setting since it might slow down the system performance after increasing the clause count.
