Multiple language items in search results

Question

We have couple of sites configured under one Sitecore instance for different languages, for example one for "Australia(en-AU)" and one for "Korea(KR)"

We are using Azure search and observing when we are performing site search the results are doubled for Australia site(all contents in Sitecore have two versions- "en" and "en-AU") i.e getting results from "en" version and "en-AU" version both. This seems to be working fine for other language i.e Korea as an example.

Search expresssion has language code added to it as filter :

Sitecore.ContentSearch.Linq.Parsing.IHasNativeQuery.Query = {Search
expression: &search=language_1:(en\-AU)&$filter=(all_templates/any(t:t
eq 'cedd694630184d5ga5453e3214985678')) and latestversion_1}

Are we missing anything here? please suggest.

Sitecore version: Sitecore 8.2 update 4

Thanks in advance!

This is a known bug for Sitecore 9. I assume it will also be present in your version.

Check here: https://kb.sitecore.net/articles/125044 The bug number in v9 is 171546.

When Azure Search performs a search query that contains a hyphen for items that are filtered by language, it returns the item for all languages. (171546)

Contact Sitecore Support and you should be able to get a patch for it.
