Filter Operations

The filter.op element defines the kind of operation to perform as a part of the filter criteria. It can take one of the following values:

Code	Display	Support
=	Equals	Supported
is-a	Is A (by subsumption)	Supported
descendent-of	Descendent Of (by subsumption)	Supported
is-not-a	Not (Is A) (by subsumption)	Supported
regex	Regular Expression	Supported
in	In Set	Supported
not-in	Not in Set	Supported
generalizes	Generalizes (by Subsumption)	Not supported
exists	Exists	Supported

In the examples below we will use the goal-status code system which consists of :

Code	Parent codes
accepted	-
achieved	["accepted"]
ahead-of-target	["accepted", "in-progress"]
behind-target	["accepted", "in-progress"]
cancelled	-
entered-in-error	-
in-progress	["accepted"]
on-hold	["accepted"]
on-target	["accepted", "in-progress"]
planned	["accepted"]
proposed	-
rejected	-
sustaining	["accepted", "in-progress"]

Equals

Let's include only concepts with the specified property code equals the provided value cancelled. The result will include only one concept: cancelled.

Regular Expression

Aidbox supports filter operation regex and implements Postgresql regular expressions. See the documentation here: https://www.postgresql.org/docs/9.3/static/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP.

Please notice that regular expressions require an additional character escaping in JSON.

Let's include codes where the specified property of the code matches the regex specified in the provided value \\w{8}. The result will include 4 values that have 8 symbols in length: proposed, accepted, achieved, and rejected.
