Change subject: Trim redundant code from TermIndex
......................................................................
Trim redundant code from TermIndex
DEPLOYMENT: heads up to ops: keep an eye on wb_terms,
some quries are now constructed differently. This
affects only queries via Special:ItemDisambiguation,
not wbentitysearch, so it should not have much impact.
