      Description

      The mistake/typo in regex used in LLD rule may cause deleting of configuration/history/events for many hosts. For example, incorrect "File systems for discovery" regular expression may cause of deleting thousands of items/triggers and history/events.

      It would be great to improve our documentation:
      1. add "important" note about this after the table with filter description (https://www.zabbix.com/documentation/2.4/manual/discovery/low_level_discovery#discovery_of_file_systems)
      2. add several additional, more complex examples in "Regular expressions" (https://www.zabbix.com/documentation/2.4/manual/regular_expressions):

      • what logical operator Zabbix uses if there are several sub expressions. OR? AND? e.g.:
        1	»	^(database,name=report)	[Result is TRUE]
        2	»	^(database,name=zabbix)	[Result is TRUE]
        3	»	^(database,name=report1)$	[Result is FALSE]

        Will "database,name=report11" pass it?

      • what about this one:
        1	»	^(database,name=zabbix|database,name=report)	[Result is TRUE]
        2	»	^(database,name=report1)$	[Result is FALSE]

        ?

      • some example with "?" or "*" metacharacters:
        1	»	^(database,name=zabbix)	[Result is TRUE]
        2	»	^(database,name=repor.*)	[Result is FALSE]

      etc
      3. Add "Combined result" description to improve "Test" tab documentation (https://www.zabbix.com/documentation/2.4/manual/regular_expressions). What does FALSE mean?
