2.Filter chaining
3=====================================================================
4It is important to note that while filters can be chained, each is linked by an
5implied logical *AND* operation.  If you want to match from one of several
6different patterns, as with a logical *OR* operation, you can do so with the
7<<filtertype_pattern,pattern>> filtertype using _regex_ as the <<fe_kind,kind>>.

9This example shows how to select multiple indices based on them beginning with
10either `alpha-`, `bravo-`, or `charlie-`:

16    kind: regex
17    value: '^(alpha-|bravo-|charlie-).*$'

20Explaining all of the different ways in which regular expressions can be used
21is outside the scope of this document, but hopefully this gives you some idea
22of how a regular expression pattern can be used when a logical *OR* is desired.
