This page documents the progress made in Q2 2020.
Overview

- The Open Food Facts mobile app (and 3rd party apps) make generic search requests that do not contain user preferences
- The server returns a big number of generic results
- The app uses the user preferences stored locally to personalize the search results
Research and specifications
At the start of the project, we evaluated the different options for server-side product indexing and search:
- Server-side product indexing and search - Functional Specs
- Server-side product indexing and search - Technical Specs
New Search API
The existing Open Food Facts search API is outdated and hacky (it was built on top of the OFF web site search form and is unnecessarily convoluted) and does not support some of the requirements for the Personal Search project (in particular being able to retrieve a given set of products using their barcodes).
We are thus creating a new Open Food Facts Search API Version 2 that will be simpler but also more powerful.
