Hi John,
Sorry, but I'll simply repeat my initial mail:

In other words, your query…
> If I modify this to my requirement it will be - ft:search("db", ("A", "B"),
> map {"mode": "phrase"})
…is equivalent to:
ft:search("db", ("A B"))
If you believe that the information in our Wiki is not clear enough
and could be improved, your feedback is more than welcome (as usual,
*any* edits to our Wiki are welcome).
Best,
Christian
