bloodhound multiple dataset cause typeahead template issue - templates

Question

I've local elastic search server, install and running.
I instanciate 2 bloodhound object followig examples (can't post link because of reputation limitations)
If I use output as is, I have my results from my 2 datasource, no trouble.
When I want to use, remote: transform or filter option, to format the data, for using a custom template, I've trouble, the 2 template never get call.
Here's my code :
First bloodhound :
var nameSuggest = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace,
queryTokenizer: Bloodhound.tokenizers.obj.whitespace,
identify: 'nameSuggest',
sufficient: 50,
remote: {
url: 'http://localhost:9200/test2/_suggest?pretty',
prepare: function (query, settings) {
settings.type = "POST";
settings.contentType = "application/json; charset=UTF-8";
search_payload = {
"suggest": {
"text": query,
"completion": {
"field": "suggest"
}
}
};
settings.data = JSON.stringify(search_payload);
return settings;
},
transform: function(response) {
return $.map(response.suggest[0].options, function (option) {
return {
optionText: option.text,
optionId:option.payload.id
};
});
}
}
});
Second dataset:
var mailSuggest = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace,
queryTokenizer: Bloodhound.tokenizers.obj.whitespace,
identify: 'mailSuggest',
sufficient: 50,
remote: {
url: 'http://localhost:9200/test2/_suggest?pretty',
prepare: function (query, settings) {
settings.type = "POST";
settings.contentType = "application/json; charset=UTF-8";
search_payload = {
"suggestMail": {
"text": query,
"completion": {
"field": "suggest2"
}
}
};
settings.data = JSON.stringify(search_payload);
return settings;
},
transform: function(response) {
return $.map(response.suggestMail[0].options, function (option) {
return {
optionText2: option.text,
optionId2:option.payload.id
};
});
}
}
});
And typeahead:
jQuery('#topSearch').typeahead({
name:'topSearch',
hint: true,
highlight: true,
limit: 20
},
{
name: 'nameSuggest',
display: 'data',
source: nameSuggest,
templates: {
header: '<div><h3 class="">Noms</h3></div>',
suggestion: function (data) {
console.log("Name");
return '<div>'+data.optionId+' - '+data.optionText+'</div>';
}
}
},
{
name: 'mailSuggest',
display: 'data',
source: mailSuggest,
templates: {
header: '<div><h3 class="">Mails</h3></div>',
suggestion: function (data) {
console.log("Mail");
return '<div>'+data.optionText2+'</div>';
}
}
}
);
When I do :
console.log(nameSuggest);
console.log(mailSuggest);
I've two separate object, with unique names (the identify option) :
Bloodhound { identify="nameSuggest", sufficient=50, local=[0], plus...}
Bloodhound { identify="mailSuggest", sufficient=50, local=[0], plus...}
but, in the remote part of each object I can see the transform and prepare section with the two object names (there are screenshot) :
first object
seconde object
If I remove transform option from both bloodhound instances, and templates for typeahead, it works, and I'v suggestions.
If I remove transform of the second bloodhound instance and template associated, first results are displayed, withing the template, and second result are displayed raw, but it works.
If I let the second template in typeahead init, without bloodhound associated transform, the second template header is displayed, but the data undefined (normal behavior I suppose).
So, somehow, transform of the second bloodhound break something, but I can't figure out what, and how.
Do I miss something, or did something wrong ?

Solved:
I have to add the size option to the query, to tell elastic to send more result:
var mailSuggest = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace,
queryTokenizer: Bloodhound.tokenizers.obj.whitespace,
identify: 'mailSuggest',
sufficient: 50,
remote: {
url: 'http://localhost:9200/test2/_suggest?pretty',
prepare: function (query, settings) {
settings.type = "POST";
settings.contentType = "application/json; charset=UTF-8";
search_payload = {
"suggestMail": {
"text": query,
"completion": {
"field": "suggest2",
"size": 20
}
}
};
settings.data = JSON.stringify(search_payload);
return settings;
},
transform: function(response) {
return $.map(response.suggestMail[0].options, function (option) {
return {
optionText2: option.text,
optionId2:option.payload.id
};
});
}
}
});
I tried with 20 for testing prupose.
