Code search

[Robsteranium]

The ulterior motive here is having a non-trivial feature to start with. This should serve to confirm we can get data out of ES and on to a web page.

The page should present a form which, when submitted, will return a list of matching codes.

We can query the code index with something like:

{ "query": { "match": { "label": "car" } } }

It might be worth investigating search templates. We can worry about semantic search/ word embeddings later.

Initially we can use the database snapshot. Maybe we could subset this (e.g. codes index only) and pop something onto s3 for CI? Once the ETL pipeline is a bit further developed, we can look at having proper fixture data.

The results could just show URI ("_id") and label for now.

Adding some sub-tasks just to keep track of implicit steps in the description above:

• [x] get some data from ES rendering on a web page in response to user input
• [ ] sanitize search input (probably? not sure what is standard for ES)
• [x] make search UI decent
  • [ ] limit results? right now just showing all of them at once (up to 10k)
• [x] figure out CI situation for ES snapshot
• [x] wire up front-end routing to ajax in new search results and update URL/manage history appropriately
• [ ] test all this new stuff
