It takes less than 1 second to run very complicated grammatical searches on the Greek New Testament, Hebrew Bible or LXX. In addition, some types of searches can be designed much more quickly in Gramcord than Logos. So for the foreseeable future, I will continue to run Gramcord for certain searches. Logos is a great general purpose tool and my day to day companion for Bible study. But some days I still need to bring out a special purpose tool to get the job done more quickly.
