Substring with case Insensitive filter is not working OData V4

Working on the filter options through ODataV4 endpoints.

In the API I have a field name called Description and it has the value.

No: "BC001",

Description: "Black poly chair"

No: "BC002",

Description: "Dining Chair "

If I search for the word "Chair". that should bring all the Items ( Case shouldn't matter).

This is the Filter Option I'm using for it.

$filter=contains(tolower(Description),'chair').

Actual URL I'm trying:

api.businesscentral.dynamics.com/.../

Note: $filter= tolower(Description) eq 'dininG chaiR ') is Working, showing empty result.

When I apply the same, under the contain option., that time only its not working.

Example : In the below example they provided the solution that is for services.odata.org. I tried the same code for filter. but still I'm getting empty result.

https://github.com/OData/ODataSamples/issues/66#issue-257575195

Can you help me for solve this.

Thank in Advance

Hello,

I am interested too - I can get this to work:

{{BaseURI}}/companies(2e396114-00ff-ea11-bc53-00155df3a615)/items?$filter=tolower(displayName) eq tolower('LONDOn Swivel Chair, blue')

but this returns nothing:

{{BaseURI}}/companies(2e396114-00ff-ea11-bc53-00155df3a615)/items?$filter=contains(tolower(displayName),tolower(%27chair%27))

I know this does not help you much, but I will try to research a bit and return here if I find out something, and meanwhile I hope others also have some ideas.

As of September 30th 2022 - This is a documented limitation, note the "Nested function calls" section in the article.

learn.microsoft.com/.../use-filter-expressions-in-odata-uris

"Nested function calls in filter clauses aren't supported in the current OData implementation. This means that filter clause expressions like contains(tolower(field), 'some') don't return the expected results - in this case a partial case-insensitive text search - but will instead either throw an error or return an undefined result."

If anyone has a way around this issue I would greatly appreciate it.

Use the @ symbol to enable case-insensitive results:

$filter=tolower(Description) eq 'dininG chaiR'

Just replying as this was top result when I was searching for an answer as this might help someone else.

I acheived this by setting an equals filter but wrap the search term in '@*....*'

So the filter above would be $filter = Description eq '@*chair*'
