Quick Filters in Piwik Pro Analytics is a feature that allows users to apply temporary filters at the report level to simplify analysis. It helps users focus on the data that matters most by enabling them to filter reports using multiple conditions. Quick Filters are used for temporary data filtering and do not modify the collected data. They currently support table types of reports, such as the 'flat table' and 'explorer table' report formats.

To apply Quick Filters to a report in Piwik Pro Analytics, follow these steps:

1. Navigate to a tabular report, such as a 'flat table' or 'explorer table' report.
2. Scroll to the table report where you'll find Quick Filters beside the search bar in the report header.
3. Click on the Quick Filters option to open a window for filter conditions configuration.
4. Click on the 'Add Condition' button to display a dropdown selection of fields and choose the metrics or dimensions for your filtering condition.
5. Select the filtering condition operator from options like 'is', 'contains', 'matches regex', etc.
6. Enter the desired value for filtering in the field provided.
7. Apply multiple filter conditions if needed, using the 'AND' logical operator by clicking the 'boxed' icon or 'Add Condition' below an already added condition.
8. Click the 'Apply' button to update the report with the applied filters.

The limitations of Quick Filters in Piwik Pro Analytics include:

1. Inability to Use the 'OR' Logical Filtering Operator: You cannot directly use an 'OR' condition between filters. However, you can use 'regular expression' (regex) to create a pattern that mimics the 'OR' functionality.

2. Inability to Select Dimensions Not Present in the Table: Quick Filters cannot be used with dimensions that are not already part of the table report. To filter using additional dimensions, you must first add them as a secondary dimension to the report.

These limitations can be addressed by understanding and applying the mentioned workarounds.
