This is the thread's initial revision.
I am working to add new features to Search Translations (link) and would like your feedback on the same. I have an idea of a new feature, called "text search with autosuggest" through which you can specify your search filters in the search box itself (apart from the UI), and also have autosuggest to show the possible values for the filter options. An example is this.
Thank you and I shall be waiting for your feedback.
