When searching, exact matches should be suggested first

[carmenbianca]

When you type in the search bar, you get a list of suggestions as you type. However, exact matches are sometimes drowned out by non-exact matches. Borrowing the example from #865:

When type "pandoc", and you get:

• pandoc-pandocker-filters
• pandoc
• jekyll-pandoc
• pandoc-numbering
• etc...

Pandoc only points to crates.io, however. If I want the PyPI package of the same name, it does not show up. Preferably, exact matches should always be suggested before non-exact matches are suggested.

This is an issue with the clearlydefined api, more precisely https://github.com/clearlydefined/service/blob/324017ef0ccfe73eb9d1593faf777d19b621a216/routes/definitions.js#L37 .

The search bar's typeahead displays suggestions in the order they appear.

To fix this, the api should return the response where the exact match appears first.
