Frank McQuillan updated MADLIB-943:
-----------------------------------
Description:
Story
As a data scientist, I want to be able to define multiple symbols per row for
pattern matching.
See
http://madlib.incubator.apache.org/docs/latest/group__grp__path.html
for a description of what a symbol is.
Currently in 1.9, a given row can only match one symbol. If a row matches
multiple symbols, the symbol that comes first in the symbol definition list
will take precedence. This story is about all matching symbols on a row being
used.
Acceptance
The attached data set and query should should produce the following output:
There are symbol matches for:
Gender=Female
Region=East
Household Size=3
