Data filters for views
Include and exclude filters
Use Include and Exclude Filters to eliminate unwanted hits.
If you apply an Exclude Filter and the pattern matches, the hit is thrown away and Analytics continues with the next hit. If the pattern does not match, the next filter is applied to that hit. You can create either a single Exclude Filter with multiple patterns separated by '|' or you can create multiple Exclude Filters with a single pattern each.
Include Filters are applied with the reverse logic. When you apply an Include Filter, the hit is thrown away if the pattern does not match the data. If you apply multiple Include Filters, the hit must match every applied Include Filter in order to save the hit. To include multiple patterns for a specific field, create a single include filter that contains all of the individual expressions separated by '|'.
Use the Case Sensitive option to specify whether the filter is applied with or without case sensitivity.
