The IRIS toolbar contains Back and Forward arrows, a Graph button, and a Query tool.
The Graph button and Query tool can be shown/hidden by clicking View->IRIS Toolbars->Query.
The back and forward arrows move you through applications (not data items) in your history.
You can view any IRIS data item and its connections in a graph. The IRIS graph allows you to follow connections and visualize your information environment from the perspective of one data item.
Note: Until you create new connections, the graph will show labels for the connections type (Projects, Tasks ...) instead of the actual connection name.
The query tool, labeled "Look for:", provides a way to find data items and drill down to the item(s) you are searching for. Start your query by selecting an item type. Optionally, you can add additional filters to further refine your query. As you add filters the List pane will reflect results for each filter added.
Clicking the word "that.." will show you the next filter choice. From the combo box that appears, choose an appropriate filter type, and then enter a value for the filter. When you press "[ENTER]", the query will activate, narrowing the query results to those that match your filter.
Note: Query is case sensitive. You may need to type "Tom" instead of "tom".
The syntax used for the queries is summarized in the following link. All features are supported except for field specification (i.e., "field1:brigham"); This feature was removed to protect IRIS's underlying indexing schema.

Here are a few highlights from the link to note about query syntax:
You can search for a group of words by surrounding them in quotes such as "hello dolly".
"OR" and "AND" are allowed between words or groupings of words. For example, "jakarta apache" OR jakarta. The OR operator finds a matching document if either of the terms exist in a document. The AND operator matches documents where both terms exist anywhere in the text of a single document.
You can also use "+" and "-". The "+" operator requires that the term exist somewhere in the field of a single document. For example, "+jakarta apache" would search for documents that must contain jakarta and may contain apache. The "-" operator excludes documents that contain the term. For example, "jakarta apache" -"Apache Lucene" would search for documents that contain "jakarta apache" but not "Apache Lucerne".
Wild cards like "*" and "?" are allowed. For example, use "te?t" to search for "text" or "test" or use "test*" to search for "test", "tests", or "tester". You cannot use the * or ? symbol as the first character of a search. For example, "*ild".
