Hi.

I have a small index of about 4000 documents. Each document has a field  
called suggestion\_name which is the title of the document. Here is what the  
relevant part of our mapping looks like:

MAPPING = {  
:properties =\> {  
:id =\> { :type =\> 'string' },  
:name =\> { :type =\> 'string', :analyzer =\> :snowball\_name, boost: 1.5 },  
:suggestion\_name =\> { :type =\> 'string', :index =\> 'not\_analyzed' },

I want to be able to provide our users a really solid "Did you mean"  
feature. I am using these phrase suggestion settings currently:

def self.suggest\_phrase(query\_string)  
self.suggest( :index =\> "special\_topics", :body =\> {  
:text =\> query\_string,  
:simple\_phrase =\> {  
:phrase =\> {  
:field =\> "suggestion\_name",  
:size =\> 1,  
:real\_word\_error\_likelihood =\> 0.95,  
:max\_errors =\> 50,  
:gram\_size =\> 2,  
:direct\_generator =\> [{  
:field =\> "suggestion\_name",  
:suggest\_mode =\> "always",  
:min\_word\_length =\> 1  
}]  
}  
}  
})  
end

But this is less than ideal. For example, a document has the title "Sports  
Massage Extreme". Mis-spelling like this work : "sports massag extreme" & "  
sprts massag extreme". But the moment I try something like this: "sprts  
massag extreeme" it fails. I have tried many, many ways to tweak the  
various knobs for the phrase suggestion but nothing seems to do the trick.  
I have tried removing the "gram\_size" param completely, adjusting the  
"max\_errors" params, etc. I have tried tweaking the direct\_generator  
various ways like increasing the "size" to 10. Nothing! What am I not  
looking at?

Thanks much!
