dojox.data.GoogleSearchStore

Status:Contributed, Draft
Version:1.4
Author:Shane O’Sullivan
Available:since V1.2

The GoogleSearchStore is actually a collection of stores designed to work with Google’s Ajax search services. GoogleSearchStore is the base class that all subclasses of GoogleSearchStore extend from. It provides all the basics of working with Google’s search API in a dojo.data compliant implementation. The following stores are avaialble for use after dojo.require() is used to load dojox.data.GoogleSearchStore:

  • dojox.data.GoogleSearchStore - The basic search store that all more fine-grained searches inherit from. This store defaults to querying Google’s Web-search Ajax calls.
  • dojox.data.GoogleWebSearchStore - A store configured to search specifically against Google’s Web search Ajax calls.
  • dojox.data.GoogleBlogSearchStore - A store configured to search specifically against Google’s Blog (Web log) search Ajax calls.
  • dojox.data.GoogleLocalSearchStore - A store configured to search specifically against Google’s Location related search Ajax calls.
  • dojox.data.GoogleVideoSearchStore - A store configured to search specifically against Google’s Video search Ajax calls.
  • dojox.data.GoogleBookSearchStore - A store configured to search specifically against Google’s Book search Ajax calls.
  • dojox.data.GoogleImageSearchStore - A store configured to search specifically against Google’s Image search Ajax calls.

Note: These stores make use of Google’s AJAX search services.. In order to use them in your web-sites, please make sure to read Google’s terms and conditions and agree to them before using these stores.

Constructor Params

The following parameters are supported by all Google store implementations.

Item Attributes

Depending on which of the search stores you instantiate, the supported list of item attributes changes. This is because each search service exposes different information, since each type of search by its nature deems specific information the key information to return. Below you will find a list of expected attribute names for each search service and what they are:

Query Syntax

The query syntax for all stores is simple. Most only take a single object with the attribute ‘text’, where the value is what text to search for.

Query Example

{
  "text" : "Find me"
}

Query Syntax for GoogleLocalSearchStore

New to Dojo 1.4, the GoogleLocalSearchStore allows for a few extra options when searching, its allowed syntax is:

{
  "text" : "Find me"
  "centerLatLong" : "48.8565,2.3509" //Comma-separated lat & long for the center of the search
  "searchSpan" : "0.065165,0.194149" //Comma-separated lat & long degrees indicating the size of the desired search area
}

Example Usage

The following example shows wiring Various GoogleSearchStores to dojox.data.DataGrids. You can type in a search string in the search box and hit search. The datagrids will then be populated with the results of the searches.

Searching multiple Google services at once

<script>
  dojo.require("dijit.form.Button");
  dojo.require("dijit.form.TextBox");
  dojo.require("dijit.layout.TabContainer");
  dojo.require("dijit.layout.ContentPane");
  dojo.require("dojox.data.GoogleSearchStore");
  dojo.require("dojox.grid.DataGrid");

  function hrefFormatter(value) {
    value = unescape(value);
    return "<a href=\"" + value + "\" target=\"_blank\">Link</a>";
  };

  var layoutResults = [
    [
      { field: "title", name: "Title", width: 20 },
      { field: "url", name: "URL", width: 5, formatter: hrefFormatter},
      { field: "content", name: "Content", width: 'auto' }
    ]
  ];

  function init() {
     //Link button to search, where search text is drawn from the input box.

     //Had to resize the grids on selection of tabs, otherwise they wouldn't always display.
     function resizeGrids() {
       dijit.byId("webGrid").resize();
       dijit.byId("newsGrid").resize();
       dijit.byId("imageGrid").resize();
     }
     dojo.connect(dijit.byId("tabSearch"), "selectChild", resizeGrids);

     function search() {
        var text = dijit.byId("searchText").getValue();
        text = dojo.trim(text);
        if (text !== "" ) {
          var query = { text: text };
          dijit.byId("webGrid").setQuery(query);
          dijit.byId("newsGrid").setQuery(query);
          dijit.byId("imageGrid").setQuery(query);
        }
     }
     dojo.connect(dijit.byId("searchButton"), "onClick", search);
  }
  dojo.addOnLoad(init);
