I tried the search after changing my settings to remove the optional hyphen and it would find "Jabeshgilead" but the word wasn't highlighted in the verse list. It wouldn't find "inhabitants of Jabeshgilead" but did find Jabeshgilead with a search for "Jabesh*" (still no highlights).
Will the hyphenation bug fix also fix word trees? Try a word tree for Bethlehem in the book of Ruth.
Could the fix work regardless of the setting in Bible Panel/Additional options? If a user module has search links/tree links, it will fail in some cases depending on the setting.
The word tree needs some special processing to match on hyphenation optionally. But once I address this issue in the module search code it should work fine across the board regardless of the search source. I am thinking that realistically, there shouldn't be a need to distinguish hyphens in a word tree, so they should probably just be ignored regardless of this setting.
