Run 2 morph searches
1) Right-click and "Search this resource" for ὥστε (eg John 3:16) SBLGNT and you will get 81 results in 81 verses
2) Do another right click search and choose "Lemma ὥστε" and search the resource will return 83
results in 83 verses.
The two missed hits by the first verse are in Luke 4:29 and 20:20. ὥστε in those contexts are preceded by apparatus symbols; looks like they are getting in the way of the selection search.
