How to use filter using the Knowledge base articles API

[Phanikanth]

Hi Team,

I have api which needs to filter the data based on query result.But unfortunately using filter not getting  the expected response .We are getting the result of unfiltered data.

https://***.service-now.com/api/sn_km_api/knowledge/articles?limit=5&query=what is laptop&filter=titleLIKESempra:L1

Expected :filter should apply only for  title field "Sempra: L1",but filter is not applying for particular condition.

I want to filter the title based sempra:L1 based records alone .please suggest the actual filter here.
