Tony Xu updated LUCENE-10048:
-----------------------------
Description:
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. Currently Lucene will skip indexing the whole document.
*"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?
