I am really surprised that a query for "behaviour" returns "behavior" as
a suggestion only when the parameter "spellcheck.onlyMorePopular=true"
is present. I re-read the documentation and I see nothing that will
imply that the parameter onlyMorePopular will do anything else but
filter the suggestions solr will return.
Maybe somebody else can shed some light on this.

Thanks. I'll have to look into modifications then (was hoping to avoid that).
For clarity though I believe this point is slightly off:
"Adding the parameter onlyMorePopular limits the suggestions that solr can give
you(to ones that return more hits than the existing query), nothing more."
The flag is definitely returning suggestions, even for 'correct' terms, they
just have to be more popular 'correct' terms.
Eg. 'behaviour' suggests 'behavior' because it has four times as many hits, but
they are both 'correct' and the suggestion does not occur without the
'onlyMorePopular' flag set. 'behavior' will not suggest 'behaviour' however
because it is less popular.

Greg,
I apologize if I misunderstood your original post. I don't think there
is a way you can force solr to return suggestions when all of the words
are "correctly" spelled. Adding the parameter onlyMorePopular limits the
suggestions that solr can give you(to ones that return more hits than
the existing query), nothing more.
In short, I believe the answer is No.

Thanks for the response Christian. I'll modify my original point (1) then. Is
'onlyMorePopular' the only way to return suggestions when all of the search
terms are present in the dictionary (ie. correct)? Is there any way to force
behaviour (1) without behaviour (2) (filtering on frequency).
Ta,
Greg

I believe your understanding in incorrect. The first behavior you
described is produced by adding the paremeter "spellcheck=true".
Suggestions will be returned regardless of whether there are results.
The only time I believe spelling suggestions might not be included is
when all of the words are spelled "correctly".

Hi All,
If I understand correctly the flag 'onlyMorePopular' encapsulates two
independent behaviours. 1) It runs spell checking across queries that returned
hits. Without the flag spell checking is not run when results are found. 2) It
limits suggestions to terms with higher frequencies.
Is there any way to get behaviour (1) without behaviour (2)? Such as another
flag I'm not seeing in the doco? The usage context is spelling suggestions for
international usage. Eg. The user searches 'behaviour', we want it to suggest
US spelling 'behavior' and vice versa. At the moment, the suggestion only works
one way.
Ta,
Greg
