There are no hard limits on the number of fields, whether they are dynamically defined or not. Several thousand fields should be no problem. If you have enough system resources and you don't run into an unlikely bug, there's no reason it won't work. As you've already been told, there are potential performance concerns. Depending on the exact nature of your queries, you might need to increase maxBooleanClauses. The only hard limitation that Lucene really has (and by extension, Solr also has that limitation) is that a single index cannot have more than about two billion documents in it - the inherent limitation on a Java "int" type. Solr can use indexes larger than this through sharding. See the very end of this page: https://lucene.apache.org/core/4_6_0/core/org/apache/lucene/codecs/lucene46/package-summary.html#Limitations Thanks, Shawn
