Logos 9.8 Mac OS 11.6
Launched search from KJV 1900 for the lemma of follow after (διώκω) and obtained 44 results in 43 verses, which is the correct response.
Altered the search string to "<Lemma = lbs/el/διώκω> WITHIN 0 WORDS persecute" and obtained 44 results in 21 verses, which is incorrect. Results should have been 22 results in 21 verses. The erroneous number of results lists the total number of times διώκω appears in the GNT, not the number of times it is translated by some form of persecute.
Changed the search string to "<Lemma = lbs/el/διώκω> WITHIN 0 WORDS follow" and obtained 20 results in 10 verses, which is double the number of actual results. If the intention had been to reveal the number of actual words used by the KJV to translate διώκω, the results should have been 14 results in 10 verses.
This indicates that the resultant count in Logos searches are unreliable.
