------------------------------------
Summary: TermWeight shoud seek terms lazily
Key: LUCENE-7311
URL: https://issues.apache.org/jira/browse/LUCENE-7311
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
Currently the terms are seeked eagerly in TermQuery.createWeight when creating
the TermContext. This might be wasteful when scores are not needed since the
query might be cached on some segments, thus seeking the term on these segments
is not needed. We could change TermWeight to only seek terms in Weight.scorer
when scores are not needed.
