# Limitations of FHIR Questionnaire Using LogicNets

Not all concepts supported by the LogicNets runtime engine can be converted to a FHIR Questionnaire. Therefore, the following limitations apply:

* LogicNets supports a limited set of parts/nodes; see [Supported Functionality](/release-9/platform-documentation/fhir-support/fhir-questionnaire-supported-functionality.md).
* Not all part parameters can be converted to FHIRQuestionnaire concepts. In the first release, which was part of LogicNets v8.0, there are no validation warnings or modeling guidance in the Designer. In the near future, the Designer will contain guidance when parameters, nodes, and/or parts are not exportable.
* LogicNets v8 does not support the following rule operators:
  * *intersects, does not intersect, overlaps, does not overlap, contains collection, equals collection, is empty, is not empty*
* The system supports the following rule operators for collections:
  * *contains, does not contain, is null, is not null*
* The system does not support conditions expressions modeled as free text; see below.
  * Note that you can convert part validation rules, switch conditions, and option conditions modeled as rules.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://community-test.logicnets.com/release-9/platform-documentation/fhir-support/limitations-of-fhir-questionnaire-using-logicnets.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
