TypeAhead.js and Bloodhound showing an odd number of results
Try initializing engine
with engine.initialize()
; returning suggestion
object at filter
, which should be available at templates
-> suggestion
; initializing engine
at source
with source:engine.ttAdapter()
; returning element as String
at suggestion
, to populate "suggestion" drop down menu . See Typeahead - examples - Custom Templates

Twitter supposedly abandoned the project. Try the maintained fork. It has the issue fixed.
If (ike me) you don't want to go into the typeahead source, (for instance because you want to use the min version) you can also set limit very high. You will then have to limit the number of items to put into the list yourself.
$('#typeahead .typeahead')
.typeahead({
hint: true,
highlight: true,
minLength: 1,
},
{
name: 'engine',
displayKey: 'fullName',
source: engine,
limit: 1000
})
There is an issue on typeahead in the code:
https://github.com/twitter/typeahead.js/issues/1218
You can change the code yourself in the JS as described on the issue page.
