I have a document library in sharepoint online and I need to have the search results show any documents that have the searched keyword appear in the file name come up first in results, (i.e. if I have a document called "Test Document", and someone searched "Test" it should be one of the first results. I've been trying to get this to work using a query rule but nothing I do fixes this issue.
Promote certain results (or the other two options listed): http://icansharepoint.com/3-simple-things-it-can-do-to-improve-sharepoint-search/ Promote Results will set certain keywords to show certain documents first.
Make sure your users know how to properly search for information; it's not 100% like googling: http://icansharepoint.com/infographic-search-sharepoint/ and more on searching: http://icansharepoint.com/how-to-improve-your-sharepoint-search-results/
