================
Comment at: clang-tools-extra/clangd/index/dex/Dex.cpp:148
+  if (TrigramIterators.size() > 1)
     TopLevelChildren.push_back(createAnd(move(TrigramIterators)));
+  else if (TrigramIterators.size() == 1)
----------------
Maybe special-case a single-iterator case in `createAnd` instead? Same with `createOr`.
Any cons to doing so?
