Sitecore Max Lucene Query Clause Count

Xing Liu • 4/14/2016

If you have encountered this following error: 

Exception: Sitecore.ContentSearch.Linq.Lucene.Exceptions.TooManyClausesException.  

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.
