lex-search

Fast search of standardized lexicons like ICD10 and Radlex, using node.js + express.js, Twitter typeahead.js and ElasticSearch

Inspired by ClinDesk icd10 search, but doing the searching server side to avoid needing to download a multi-MB file to the client. This also theoretically allows many more lexicons to be added without affecting performance on the client.

Install

Clone the repository, then in the repo directory:

npm install

npm install -g webpack

npm run build

npm start

Go to localhost:3000

Building

For development, use

npm run watch

This will use the development version of React, and watch for changes.

For prodution, use

npm run build

which just adds the NODE_ENV=production flag to the build, which builds the production version of React, which is smaller and with fewer warnings.

Sources

Two lexicons are currently included, ICD-10 and Radlex, the radiology lexicon.

The original source documents are parsed using the included scripts into JSON with the following format:

[
  {
    "i": String, // Unique string identifier, i.e. id of element in lexicon
    "d": String, // Description of the element, i.e. the common name
    "n": Array, // ["extra notes", "or alternative phrases", "will also be indexed for search"]
  },
  {...}
]

The elasticsearch index is pre-built with node build-elasticsearch-index.js
