Search Bar The quickest way to search the database is to begin typing in the search bar. You'll be presented with database terminology which you can use to create one or more simple filters. The search bar also acts as an aggregator of all currently enabled filters.
Search Tools There are a number tools you can use to explore the database, which are described in detail below.
Search Results Whenever you change any search filters, the updated search results will be listed here. You can link to a resource's report, zoom to it on the map, or view its related resources.
Search Panel The contents of this panel will change depending on what search tool you are using. Typically, the map will be activated by default.
Search results can be represented on the map in two ways: markers show the first set of resources in the search results, and cells are used to give a general spatial representation of all resources in the search results.
In addition to displaying search results, the map can show resource layers (showing all resources), or custom overlays, if any have been added. You control the visibility of all layers and basemaps with the tool panel on the right.
Finally, you can add a spatial filter to your query by using the map drawing tools to draw a shape and apply a buffer distance if desired.
You can apply a temporal criterion to your query by using the Time Filter. You have the option of creating the filter by hand, or you can use the time wheel. The time wheel is a graphic representation of all the resources in the database, organized chronologically.
Saved searches allow you to view pre-made queries. Saved searches are created by database administrators, so the number of saved searches shown here will vary from one database to the next.
You can use the advanced search to make more complex queries based on data attributes, or "facets". While the basic search filter allows you to combine multiple filters, advanced search is the only way to combine filters with an or operator, and also gives you access to more comparison operators.
In the example below, a search is made within a single resource type for any name like "church" or any name like "gate".
For each resource listed in the search results you can view its related resources with the "Related Resources" link under the description. By viewing Related Resources, you get a new view of the database: not how resources are related geographically nor chronologically, but qualitatively.
There two methods for viewing Related Resources: in a table where each related resource is a row, or in a graph where resources are shown as nodes in a graph, with relationships connecting them.
