Indexing / ISO / Properly index all keywords even if in different

thesaurus block

Fixes #7841

Use the current-group which contains all grouped blocks.
Also fix record view which in this case was repeating keywords because
the `otherKeywords-` prefix was matching other thesaurus key eg
`otherKeywords-place`.
