Class: searchDirective directive:gmfSearch

A directive that allows to search and recenter on a selected result's feature. It can search in multiple GeoJSON datasources. It can filter and group results by a feature's property.

This directive uses the ngeo.FeatureOverlayMgr to create a feature overlay for drawing features on the map. The application is responsible to initialize the ngeo.FeatureOverlayMgr with the map.

Example flat results:

 <gmf-search gmf-search-map="ctrl.map"
   gmf-search-options="ctrl.searchOptions"
   gmf-search-styles="ctrl.searchStyles"
   gmf-search-datasources="ctrl.searchDatasources"
   gmf-search-coordinatesprojections="ctrl.searchCoordinatesProjections"
   gmf-search-delay="mainCtrl.searchDelay"
   gmf-search-clearbutton="true">
 </gmf-search>
 <script>
   (function() {
     let module = angular.module('app');
     module.value('fulltextsearchUrl', '${request.route_url('fulltextsearch', _query={"limit": 20, "ranksystem": "similarity"}) | n}');
     module.value('gmfSearchGroups', []);
     module.constant('gmfSearchActions', [
           {action: 'add_theme', title: 'Add a theme'},
           {action: 'add_group', title: 'Add a sub theme'},
           {action: 'add_layer', title: 'Add a layer'}
     ]);
   })();
 </script>

Example with categories:

 <gmf-search gmf-search-map="ctrl.map"
   gmf-search-options="ctrl.searchOptions"
   gmf-search-styles="ctrl.searchStyles"
   gmf-search-datasources="ctrl.searchDatasources"
   gmf-search-coordinatesprojections="ctrl.searchCoordinatesProjections"
   gmf-search-clearbutton="true"
   gmf-search-delay="mainCtrl.searchDelay"
   gmf-search-colorchooser="true">
 </gmf-search>
 <script>
   (function() {
     let module = angular.module('app');
     module.value('fulltextsearchUrl', '${request.route_url('fulltextsearch', _query={"limit": 30, "partitionlimit": 5}) | n}');
     module.value('gmfSearchGroups', ${dumps(fulltextsearch_groups) | n});
     module.value('gmfSearchActions', []);
   })();
 </script>

The 'fulltextsearchUrl' value in the examples above set three "_query" parameters: "limit", "partitionlimit" and "ranksystem". For this last one "similarity" is the only effective value. It's used to order your search results with the "similarity" ranking system from PostgreSQL module pg_trgm. Without this value, the PostgreSQL function "ts_rank_cd" is used for the ranking. Read the full-text search c2cgeoportal documentation to know more. You can also add these parameters to the "url" variable of one (or more) of the gmfx.SearchDirectiveDatasource given to this component (here within the "ctrl.searchDatasources"). That allows you to have multiples configurations on one search component.
