             Summary: Bypass total frequency check if field uses custom term frequency
                 Key: LUCENE-10048
                 URL: https://issues.apache.org/jira/browse/LUCENE-10048
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Tony Xu


For all fields whose index option is not *IndexOptions.NONE*. There is a check on per field total token count (i.e. field-length) to ensure we don't index too many tokens. This is done by accumulating the token's *TermFrequencyAttribute.*

 

**Given that currently Lucene allows custom term frequency attached to each token and the usage of the frequency can be pretty wild. It is possible to have the following case where the check fails with only a few tokens that have large frequencies.

*"foo|<very large number> bar|<very large number>"*

 

What should be way to inform the indexing chain not to check the field length?

A related observation, when custom term frequency is in use, user is not likely to use the similarity for this field. Maybe we can offer a way to specify that, too?
