Searching


Differences from Omeka

AvantSearch completely overrides Omeka's public search features. It provides its own Advanced Search page and presents search results in a wide variety of ways. It does not affect Omeka's admin search. The table below highlights the differences between AvantSearch and Omeka's native search.

Quick Search is a feature of Simple Search that allows you to immediately go to the page for an item by typing the item's Identifier value in the simple search box. This is much faster than getting back search results for every item that contains that value and then having to locate and click on the item of interest.

The AvantSearch version of simple search improves on the native Omeka simple search by only returning results that contain all of the matching keywords instead of any of the keywords. Items that contain some, but not all of the keywords will not appear in the results. Searching for all keywords tends to provide much more relevant results. If you need to search for any of the keywords, you can enter the keywords on the Advanced Search page and choose the Boolean condition.

Search Results Views

One of the most powerful features of AvantSearch is its ability to display search results in many different ways which you can customize to meet your needs. In addition to the Index View presentation described later, the Table View lets you specify any number of different layouts to display results in rows and sortable columns. The screen shots that follow show the same AvantSearch results in three different Table View layouts.

Table View

Table View Detail Layout

The Detail Layout provides a compact presentation of key information about an item including a thumbnail image. You specify which elements appear in the two columns to the right of the thumbnail. The item's description automatically appears in the third column. The screen shot below is truncated after the first three results.

Summary Layout Example


Table View Custom Layouts

This is an example of a custom layout showing the item's Type and Subject elements. The red triangle next to 'Type' in the header indicates that the results are sorted ascending by Type. The screen shot below is truncated after the first 10 results.

Custom Layout Example


This is another example of a custom layout, but this one shows the item's Creator and Publisher elements. Note the asterisk on item 2636. When you are logged in as an administrator, the astersisk indicates that the item is not public. When not logged in, the item does not appear in the results. You can also define layouts that can only be chosen when logged in. These layout can be used to show data that is normally hidden from public users. The screen shot below is truncated after the first 10 results.

Custom Layout Example

Image View

Image View displays search results as a grid of thumbnails. It's a more compact way to view results when the image is most important for identifying items of interest. The screen shot below is truncated after the first 10 results.

Image View Example

Index View

Index View displays information like the index in a book. It consolidates values into unique groups having the same value. The screen shot below is truncated midway through the B's.

When the index field contains hierarchical data, Index View shows only the leaf (lowest level) values in the hierarchhy. For non-hierarchical data, Index View shows the entire value. The data is considered to be hierarchical only if the index field element is specified using the Hierarchies option, otherwise Index View displays it as flat data.

Index View Example

Both the Table View Detail Layout and the Image View display thumbnails for an item's image if it has one. If the item has no image, a placeholder image is displayed. When you click on a thumbnail, the AvantSearch plugin displays a large version of the image. You can have the image display in a popup by using the Lightbox feature of the [AvantCommon] plugin.

Lightbox Example

Advanced Search Page

AvantSearch provides its own Advanced Search page. You access this page by either clicking on the Advanced Search link that appears below the simple search box in the header of every page, or by clicking the Modify Search button that appears on search result pages.

The screen shot below shows the search conditions that were specified to generate the Table View Custom Layout - Type / Subject screen shot shown earlier.

Advanced Search Page

Date Range Feature

When AvantCommon is configured to provide Start and End years, year start and end text boxes will appear as filters at the bottom of the Advanced Search page. A user can provide values for both the start and end years to limit search results to items in that range inclusive. For example if you specify 1900 for the start year and 1940 for end year, search will find items with start year greater than or equal to 1900 and less than or equal to 1940. If you only provide a value for the start year, the search will find items where the start year is that date or more recent. If you only provide a value for the end year, the filter will find items where the end year is that date or older.
