A site I have in development (WP 3.5.1) uses both Relevanssi 3.1.4 and WP Glossary 1.5.1. Relevanssi replaces the normal WP search, when I do a site search the results are as they should be but also show one WP glossary term. Specifically, the one listed last alphabetically.
If I create a new item in WP Glossary called zzzzzz (I'm not kidding), a search results page of Relevanssi álways shows zzzzz as one of the results (usually top 5). Deactivating Relevanssi solves the problem, the normal WordPress Search module does not show the WP Glossary item.
Excluding the alphabetically last item of WP Glossary does not work, then the second last item will always be shown. If anyone has a fix, or at least a vague direction of where I should look, I would be so grateful. Its not a big issue, but its puzzling and annoying.
