FIX: search index failing on certain posts (#20736)
During search indexing we "stuff" the index with additional keywords for
entities that look like domain names.

This allows searches for `cnn` to find URLs for `www.cnn.com`

The search stuffing attempted to keep indexes aligned at the correct positions
by remapping the indexed terms. However under certain edge cases a single
word can stem into 2 different lexemes. If this happened we had an off by
one which caused the entire indexing to fail.

We work around this edge case (and carry incorrect index positions) for cases
like this. It is unlikely to impact search quality at all given index position
makes almost no difference in the search algorithm.
