Solr / Lucene多值字段-值的最大数量？

Question

Is there an actual or practical limit to the number of values that can be placed in a multivalued field in Solr/Lucene?

For example, if I want to have an indexed field with 5000 numeric values, will this cause problems?

Thanks.

Answer 1

You question requires bit more context. It depends on how the field will be used.. Apparently going by the amount of data in the field, features like faceting wont make much sense..

Performance wise, it might be worth noting,

• Document Cache will take up relatively more memory.
• if it is part of copyField you have to careful about potential index size increase.

There is no definitive answer, the best is to create test data set & benchmark it with what you intend to do & see the behavior.
