fix or deprecate TermsEnum.seek
-------------------------------
Key: LUCENE-1592
URL: https://issues.apache.org/jira/browse/LUCENE-1592
Project: Lucene - Java
Issue Type: Improvement
Components: Index
Reporter: Michael McCandless
Priority: Minor
Fix For: 2.9
This method is a trap: it looks legitimate but it has hideously poor
performance (simple linear scan implemented in the TermsEnum base class since
none of the concrete impls override it with a more efficient implementation).
The least we should do for 2.9 is deprecate the method with a strong warning
about its performance.
