Now that I think about it, does the prefix search still work with that hack? By work I mean you should be able to select one of the entries that pops down under the search box as you type and it takes you to that article.
No, with the hack in place clicking on one of the drop down search suggestions takes you to the search results page for that value, not to an article page. That _is_ perhaps what I want. I want Search to take you to a search results page, so that a user may choose which page he wants.
Is the drop down list of search suggestions generated from a list of the wiki's page titles? Hm, I guess it is. I had not realized that. So how does one search the wiki's page texts? This whole search feature seems to be designed to take a user to a destination article directly whenever possible. I'm not sure that is best for my wiki because that page may not always be the one a user wants and without the search results page, how will he find the one he does want? By doing another search with more search terms? Hm, maybe we can all get used to this and maybe it will just work.
Argggg, and trying to change this designed in behavior may not be so easy for a chiefly point and click guy like me.
So I may decide to use the two button ('Go' + 'Search') Search box that I get when I set $wgVectorUseSimpleSearch to false, instead, especially if this hack is not going to work in future.
Thanks for the tips.
