Metadata

[roberto-belardo]

Hi, I tried to use the API getMetadata to get the number of results for a certain search but I can get it working. Could you provide a working example?

I defined an helper:

Template.toursSearchResults.helpers({
  meta: function() {
    console.log("METADATA: " + TourSearch.getMetadata());
    return TourSearch.getMetadata();
  }
});

I defined a server searchSource:

SearchSource.defineSource('tours', function(searchText, options) {
  var options = {sort: {submitted: -1}, limit: 20};
  if(searchText) {
   var regExp = buildRegExp(searchText);
   var selector = {$or: [
     {title: regExp},
     {summary: regExp}
   ]};
   return Tours.find(selector, options).fetch();
//  var data = getSearchResult(searchText);
//  var metadata = getMetadata();

//  return {
//    data: data,
//    metadata: metadata
//  }
 } else {
   return Tours.find({}, options).fetch();
 }
});

function buildRegExp(searchText) {
  // this is a dumb implementation
  var parts = searchText.trim().split(/[ \-\:]+/);
  return new RegExp("(" + parts.join('|') + ")", "ig");
}

And i am calling the search in the helper at the keyup as in you example:

Template.toursSearchBox.events({
  "keyup #search-box": _.throttle(function(e) {
    var text = $(e.target).val().trim();
    TourSearch.search(text);
  }, 200)
});

But i cannot get the metadata. In the browser console i get an empty metadata object. If i uncomment the getMetadata() call in the searchSource server side definition I get a getMetadata is not defined.

Could you help me understand where is the error?

Thank you for your great job!

You should define which data you want to have in metadata in the Server side. Example:

SearchSource.defineSource('meals', function(searchText, options){
  var options = options ? options : {sort: {_id: -1}, limit: 5};
  var selector = {}
  if (searchText){
    var regExp = buildRegExp(searchText);
    selector = {$or: [
      {title: regExp},
      {description: regExp}
    ]};
  }
  var query = Tours.find(selector, options);
  return {
    data: query.fetch(),
    metadata: {count: query.count()}
  }
});
