Where we buy two or more databases from the same service, such as EbscoHost or ProQuest you can simultaneously cross-search them by selecting the Choose Databases link above the search box, or in the top menu bar and choosing the appropriate ones.
Try using "..." around common phrases such as "project management" to retrieve the exact phrase
Try using the truncation symbol * to retrieve all variant endings of words. e.g. work* will find work, works, worker, workers, working, workplace, etc.
When using the ProQuest databases change the end menu from 'Anywhere' to 'Anywhere except full text'
When using the Sage or Emerald databases, tick the radio button for 'Only content to which I have full access'
