Trouble filtering zendesk articles by locale

I am developing for my work a spa based on Zendesk API calls. And I have encountered a problem, I am using the search articles call to get the information of all the articles and I need to make a filter by locale (language), the problem is that I want to keep my source_locale in en-us but it replaces this by es-es for example. Is there any way to use the search but to search by locale and not by the search_locale. I have found another option too which would be the list articles. But this one leads me to another problem, I need to filter the articles by label_names but using many, that is, for example I need to search articles that have either one or another label [home_page, category_page]. But I have read that the list articles only searches by ANDing the labels...but I need an OR.

Thanks for your help
