Hi all,

I have created an index using wikipeida river, which possesses a mapping as  
follows.

mappings: {  
page: {  
properties: {  
title: {  
type: string  
}text: {  
type: string  
}disambiguation: {  
type: boolean  
}category: {  
type: string  
}stub: {  
type: boolean  
}link: {  
type: string  
}special: {  
type: boolean  
}redirect: {  
type: boolean  
}  
}  
}

As you may find, there are some boolean field.  
Now I want to filter the documents with the "disambiguation" filter is  
true, but I can't find which filter I can make use of.

Thanks for your help.
