Hi Power BI community,
I am currently impelmenting a Q&A solution for some ad-hoc reporting.
So I understand all the UI things that can be done to build some ontology between the columns and the business unterstanding, i.e. renaming columns, using synonyms or defining adjectives with the Teach Q&A feature.
So my understanding is that with the linguistic schema we can define phrasings. For example "what have my customers bought". So we would define the verb [buy,purchase] and set the Subject as customertable.customer and the Object as producttable.product.
At the moment the documentation on this topic is really sparse. For example to me it is not clear what Operators are valid for Conditions for example. In the doc I could only find "Equals", but how do we write ">", "<", or "<>" in the schema?
The only useful documentation that I could find is here:
https://powerbi.microsoft.com/en-us/blog/editing-q-a-linguistic-schemas/
https://docs.microsoft.com/de-de/power-bi/natural-language/q-and-a-tooling-advanced
Does anyone have other sources? For me this is not really enough, and only offers information for the presented cases. I think Microsoft should really provide better documentation on this topic. I am also not sure if lingusitic schemas that are now developed, will still be working in the future once the feature goes into public availability.

With this tool you can see what are the valid values that you can fill into the YAML file. Probably a better alternative to using VS Code.
Greetings,
