Quick search and Advanced Search term suggestions are formatted differently

[kimrutherford]

While fixing #2180 I got quite confused because the quick search suggestions are formatted differently than the advanced search suggestion. I initially thought they were returning different results and couldn't work out why.

The advanced search shows the matching synonym but not the term name. The quick search does the opposite. Also only the quick search highlights the matching words in the definition.

At some point I'd like to improve this.
