Problem

You get an error com.ibm.commerce.catalog.facade.client.CatalogNavigationViewException on the Commerce server or the following error on the Solr server:

SolrCore E org.apache.solr.common.SolrException log org.apache.solr.common.SolrException:
      org.apache.lucene.queryParser.ParseException:
      Cannot parse 'catentry_id:("123456" ....  )': too many boolean clauses

Possible cause

You have a large number of SKUs per product during product entitlement.

Possible solution

Increase the MaxBooleanClause property in solrconfig.xml to 8192. Keep in mind, that each index has its own solrconfig.xml file with the maxBooleanClauses setting.
