Autodesk Forge 查看器，搜索

Question

I am using Autodesk Forge Viewer.

viewer.search('"' + keyword +'"', function(e)
{
    viewer.select(e);
    viewer.fitToView(e);
}

I am searching like this. The problem is that it searches for both "SG-100" and "SSG-100". I only want to search for SG-100.

How can I do this? Help!

Answer 1

My suggestion would be to do a second filter inside the search:

viewer.search(keyword, (dbIds) => {
   // success
   viewer.getBulkProperties(dbIds, ['AttributeName'], (elements) => {
      let dbIdsToSelect = [];
      for(var i=0; i<elements.length; i++){
         if (elements[i].properties[0].displayValue===keyword)
            dbIdsToSelect.push(elements[i].dbId;
      }

      viewer.select(dbIdsToSelect);
      viewer.fitToView(dbIdsToSelect);
   }
}, (e) => {
   // error, handle here...
}, ['AttributeName']);

I agree with Augusto's suggestion that you'd need to limit the search scope to specific properties only to avoid partial matches. According to the search function description it's supposed to do just that if you provide the list of property names in the 4th argument that is called ' attributeNames '. Unfortunately, from my experience, that does not work, so you need a second level filtering by using a getBulkProperties function that will reduce the list of dbIds from the search to only those that have specific properties defined. Pay attention, that the search method belong to the viewer object but the getBulkProperties method belongs to the viewer.model object.
