This flexibility in versioning can help content authors and developers easily manage and control the evolution of a page over time.

4 min readTo apply $lookup with conditions in MongoDB, you can use the aggregate pipeline stages to match documents in the foreign collection based on certain conditions. You can use the $lookup stage to perform a left outer join between two collections and then apply additional conditions using the $match stage to filter the results. For example, you can specify a matching condition in the $match stage to only include documents from the foreign collection that meet certain criteria.

3 min readTo run a PowerShell script in a path with spaces, you will need to enclose the file path within double quotation marks. This is necessary because PowerShell treats spaces as delimiters, so enclosing the path in double quotes ensures that the entire path is treated as a single entity. For example, if your script is located at "C:\My Scripts\test_script.ps1", you would run it by typing ".\C:\My Scripts\test_script.ps1" in the PowerShell console.

6 min readTo find the location of the generated CSS file on Adobe Experience Manager (AEM), you can navigate to the CRX DE Lite tool within AEM. Once in CRX DE Lite, locate the specific component or page that contains the CSS file you are looking for. From there, you can usually find the CSS file within the component's folder structure. Alternatively, you can use the browser's developer tools to inspect the rendered page and identify the CSS files being used.

4 min readTo access nested arrays in MongoDB, you can use dot notation to navigate through the objects within the arrays.
-
6 min readTo filter PowerShell SSH output, you can use built-in cmdlets such as Select-String or Where-Object. Select-String can be used to search for specific patterns in the output, while Where-Object can be used to filter output based on conditions. You can also pipe the output to other cmdlets such as Sort-Object or Format-Table to further manipulate or format the data. Additionally, you can use regular expressions with Select-String to perform more complex filtering tasks.

5 min readSession management across a clustered environment in AEM involves ensuring that user sessions are maintained and synchronized across multiple instances of the AEM application. This typically involves using a shared session store, such as a database, to store session information that can be accessed by all instances in the cluster.

6 min readTo count or sum an array in MongoDB, you can use the aggregation framework which provides powerful tools for data analysis. You can use the $unwind operator to flatten the array, $group operator to group the flattened documents and apply the $sum operator to calculate the total sum. Another option is to use the $size operator to get the count of elements in the array. By combining these operators in the aggregation pipeline, you can perform counting and summing operations on arrays in MongoDB.

6 min readTo join two collections in MongoDB, you can use the $lookup aggregation operator. This operator allows you to perform a left outer join between two collections based on a common field. By using $lookup, you can combine documents from both collections into a single result set.When using $lookup, you specify the name of the collection you want to join with, as well as the field that will be used to match documents from the two collections.

4 min readTo update the value of a field for all pages in AEM, you can create a workflow that loops through all the pages and updates the field with the new value. You can either use the OOTB functionalities in AEM to create a workflow for this purpose or write a custom workflow that handles the update operation. Make sure to test the workflow on a smaller set of pages before running it on all pages to avoid any unintended consequences.
