Activation: The Principle of Segment Retrieval

After you have assigned codes to document segments, you will be able to call up all segments that were coded with the same code. MAXQDA offers various ways to do this retrieval, but it is all based on activation of documents and codes.

The retrieval principle in MAXQDA is very simple:

All segments from activated documents that were coded with any of the activated codes will be called up and shown in the “Retrieved Segments” window.

Activating documents

First the documents: All documents and document groups are listed in the “Document System”. The starting point, then, is an inactivated document. The current state of the activation can be recognized by the color of the document name and the document symbol: Activated documents are displayed in red and the grey circle in front of them changes to a red arrow.

As soon as at least one document is activated in a document group, a red arrow also appears in front of the document group symbol:

There are several ways to activate documents:

1. Activation with the mouse

The easiest way to activate a document is with the mouse: Click with the left mouse button on the symbol of a document to activate it. Alternatively, you can click on the grey circle in front of the document symbol or on the displayed number of coded segments at the end of each document row.

All documents in a document group or document set can be activated in the same way: To do this, click on the folder icon of the document group or document set. All the documents in the project can also be activated with a single click by clicking on the folder symbol of the "Documents" entry at the top of the "Document System".

2. Activation via the context menu

You can also activate a document via the context menu: Right-click the document name or icon and choose Activate from the context menu.

In the same way, you can also activate all documents of a document group or document set at the same time by right-clicking the group or set and selecting Activate All documents. This menu entry is also available at the very top level, "Documents", the root of the Document System.

3. Activation with the Ctrl or cmd Key

Similar to selecting files in Windows Explorer or Mac Finder, you can also hold down the Ctrl key (Windows) or ⌘ key (macOS) and click on the required document, document group, or document set with the left mouse key.

Activating codes

Activating codes works in the same way as for documents. Either right-click on a code and click Activate in the context menu or click on the all symbols of the codes you want to activate.

Activating a code via the context menu

The activation of the codes is also indicated by a red arrow and the red color of the code name.

Tip: If you hold down the keys Ctrl+⇧ (Windows) or ⌘+⇧ (macOS) when clicking a parent code, only the parent code and not its subcodes are activated.

The status bar at the bottom of the MAXQDA window gives you information about the number of activated documents, activated codes, and the number of document segments that are being called up based on those activations.

Compiling coded segments in the "Retrieved Segments" window

All of the document segments that were found based on your activations are called retrieved segments or coded segments and are displayed in the “Retrieved Segments” window - if it is currently open.

More activation methods

Activation via search in document and code names

Both in the "Document System" and in the "Code System" a local search for document and code names can be performed. If you click on the magnifying glass in the window title of the "Code System", the following search bar appears:

Activate code names with search hits

By clicking on the red symbol Activate codes with search hits (far right) all codes are activated in the example where the searched word occurs. This process overwrites the previous activation status.

Activating by variables

Activating documents and codes can done manually, but also automatically depending on certain variable values. This type of activation is referred to in MAXQDA as Logical Activation or Activation via Document and Code Variables, and is described in detail here.

Activating by color

Documents and codes can be activated not only manually (by clicking them) and automatically (by document and code variables), but also by color. In both the "Document System" and "Code System" windows you will find the Activate by Color entry in the context menu that appears when you click on the top entry of the hierarchical "tree", More... > Activate Documents/Codes by Color.

A dialog field will appear with all the colors that have been used for documents/codes so far. You can then check the box next to the colors to be activated. The two buttons at the top also let you check or uncheck all of the colors with a single click.

The colors representing codes or documents to be activated

Activate documents by random

In addition to activation with variables and colors, documents can also be randomly selected. Right-click on the root of the documents and choose More... > Activate Documents by Random.

In the dialog that appears, MAXQDA displays how many documents are available in the project and allows you to enter a number of documents to be activated.

Activation of documents depending on code distribution

To activate all documents in which a selected code or one of it's subcodes exists at least once, right-click the code in the code system and choose Activate Documents with this Code or Activate Documents with this Code, respectively, from the context menu. The current activation in the "Document System" will then be overwritten.

To activate all documents in which a selected code or one of it's subcodes exists at least once, right-click the code in the code system and choose Activate Documents with this Code or Activate Documents with this Code incl. Subcodes from the context menu. The current activation in the "Document System" will then be overwritten.

Resetting activations

Cancelling the activation of documents or codes operates on the same principle as activation: either via the context menu or with the mouse (eventually using the Ctrl or ⌘ key.) When you want to start a new Coding Query, but already have documents and codes activated from a previous retrieval, the easiest way to proceed is to automatically deactivate all of those documents and codes.

In the Start tab, you will find a Reset Activations button, which fulfills this function.

Button to “Reset activations”

If you want to reset activations for only the documents or only the codes, you can do so with the button available in the “Document System” or “Code System” toolbars.

Button to “Reset activations” for all documents in the “Document System”
Button to “Reset activations” for all codes in the “Code System”

It is also possible to deactivate all codes or documents by right-clicking on the Documents icon in the “Document System” or the Codes icon in the “Code System” and selecting Deactivate all documents or Deactivate all, respectively.
