[sword-devel] SWORD search issue / search type multi Word

[Tobias Klein]

I have a finding regarding the search results.

Module: NASB

Search term: "faith Jesus"

Search type: multiWord (-2)

Search boundaries: Regular (without strict flag)

Among others I get Ephesians 2:7 and Ephesians 3:11 as search results. 
Both contain the word "Jesus".
However, the respective second verse (Ephesians 2:8 and Ephesians 3:12) 
which does contain the word "faith" is not returned as a search result 
even though I would expect it here.

Best regards,
Tobias
