You can find my opinions and suggestions point by point.

I think it depends on how many content you have to search in. If you 
have a great number of resources I think a search index should be more 
suitable.

You can use the setSort method, like in the following example:

Sort thisSort = new Sort();
// false = normal order (asc), true = inverse order (desc)
thisSort.setSort(new SortField("YourSorterField", SortField.STRING, true));
search.setSortOrder(thisSort);

If you use OpenCms categories you can use the collector 
allKeyValuePairFiltered or timeFrameAndCategories (you can find a 
complete list of collectors on 
http://www.opencms-wiki.org/wiki/The_OpenCms_8_Demo_Template_Modules_in_Detail).

If you don't use categories you can loop the contents and make a test by 
comparing the input value form with the value of resource content.

Best regards

Antonio
