Add a findByName filter for results inside other results

findByName returns results contained in folder that are also results. e.g., a search for 'asthma' returns both the 'asthma' diagnosis folder and all its individual children (e.g., 'cheese-maker's asthma'). This increases the number of results by several orders of magnitude. Add a reducedResults boolean flag to findByName that removes these terms. This will correlate with a "show individual items in folders" checkbox in the webclient.
