The system will search for the keywords in the properties that you've checked and rank the results similar to a search engine

The results will be displayed in the Search Results pane. If the search query hits more than 200 results, then only the top 200 will be displayed.

If you provide more than one keyword, the system will search for items that have all the keywords.

Wildcards: You may also use wildcard character * . see examples.

OR operator : It's possible to have the results that have either one or another keyword. Please see the example 4.

Quick Search Help

Quick search helps you quickly navigate to a particular category. It searches only the titles and it works by starting to search as you type and provide you options in a dynamic dropdown list.

You may use this feature by simply typing the keywords that you're looking for and clicking on one of the items that appear in the dropdown list. The system will automatically load the item that you've picked.

You may as well use wildcards to find similar words or to simply save some typing.

For example, tuber* confirmed will hit both tuberculosis and tuberculous together with the word 'confirmed'

The colored squares show from where the results are found.
(green:Title, blue:inclusions
You don't need to remember the colors as you may hover your mouse on these squares to read the source.

Visualization Modes


When visualizing the foundation, all nodes look the same except the selected entity which has a darker background and larger circle. In this example the Intervertebral disc herniation is the selected entity


When browsing a linearization, only entities in that linearization are visible. Regular parent-child relations are shown in blue color. The foundation children that are not linearization children are shown with a dashed line in gray.

The color within the circle shows whether the entity is a grouping entity or a category with a code

Linearization within foundation

If you click on the button, the system displays the system shows you the foundation but highlighting the linearization within the foundation.

In this mode, the entities that are in the linearization has a blue circle whereas entities that are not in the linearization has a gray circle. As in the linearization view, the color inside circle shows whether the entity is a grouping or a codable category

The blue lines show the linearization parents where as the gray lines are other parent-child relations in the foundation

In this example, "Polycythaemia" has 3 children in the foundation.

One of them (the one with the gray circle) is not included in the linearization.

"Relative polycythaemia" is included in the linearization but the linearization parent is elsewhere (blue node with gray connection).

The third one is a proper linearization children (blue circle with blue line)
