For scripture citation search, a drop down menu will show all the available citations as soon as you start to type.
For fulltext search, type in any keywords that come to mind, and the search engine will return results ranked by relevancy. You can also use some special keystrokes to refine your search. They include:
|" " (double quotation marks)||search for a phrase|
|* (asterisk)||search with a wildcard|
|+ (plus sign)||require that the word or phrase be present in all results|
|- (minus sign)||require that the word or phrase NOT be present in any results|
|~ (tilde)||make the word or phrase fall lower in the results; acts like the - (minus) symbol without entirely removing the word or phrase from the results|
