             Summary: CompressingTermVectors termsEnum should probably not support seek-by-ord
                 Key: LUCENE-5156
                 URL: https://issues.apache.org/jira/browse/LUCENE-5156
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


Just like term vectors before it, it has a O(n) seek-by-term. 

But this one also advertises a seek-by-ord, only this is also O(n).

This could cause e.g. checkindex to be very slow, because if termsenum supports ord it does
a bunch of seeking tests. (Another solution would be to leave it, and add a boolean so checkindex
never does seeking tests for term vectors, only real fields).

However, I think its also kinda a trap, in my opinion if seek-by-ord is supported anywhere,
you kinda expect it to be faster than linear time...?
