"Prevent returning search results with match percentage less than the minimum score specified in the Translation Memory settings"

SDL MultiTrans translation provider plugin: show matches above the minimum match value only

The MultiTrans translation provider plugin will display segments in the lookup window whose match percentage is below the minimum match value defined in the project settings. Often you will get segment with e.g. 25% match while the minimum match value is set to 70%. This should be fixed to respect the minimum match value.
