Hi Peta.
1.- "When the Search full text option is unchecked, full text is still searched (e.g. concept name, keywords and definition), resulting In an unnecessarily large number of search results."
Wrong, Search full text unchecked = Search Concept (and Keywords) only (not definition)
2.- "Search results are displayed in alphabetical order and only concept names are shown, meaning that staff cannot filter the results by reading ahead."
"only concept names are shown" this depends how you have set up your Glossary display. I suppose you have set it to display "Entry list". If you set it to display "Dictionary style", you will display both Concept word and Definition.
