AI Search returns inconsistent results

[Bernard Esterhu]

We are evaluating AI Search.

I have indexed the complete Incident table (indexed source) - I can confirm that all my incidents have been indexed. I have mapped short_description to title, and description to text.

I use this indexed source in my Search Source with no filters or conditions

I use the Search Source in my Search Profile.
I now test the AI Search in AI Search -> Preview -> Search Preview.
I have these three incidents (with short description):

• OLA Test
• Test OLA
• Test Email OLA

If I search for "ola", only one result is returned:

However, if i search for "ola test", those three are returned, including many other incidents with "test" in the short description.

How can this logic be explained?

A couple of things to check. First, AI Search does not support field level ACLs, so if there are matches on those fields, they are not included in search. It is possible that OLA appears in other fields of the 1 record that is returned, but not in the others. 

The reason why there is a high number of test matches in the second screenshot is likely caused by the AND to OR behavior for query resubmission.
