@nxus/searcher

Build Status

The Searcher module enables easy searching of Nxus models using different adapters for Solr, ElasticSearch and others.

Installation

> npm install @nxus/searcher --save

Usage

Configuration

The Searcher module depends on @nxus/storage. The first step is adding and configuring the search adapter you'd like to use. For example, if we want to enable ElasticSearch, we first install the waterline-elasticsearch adapter, then setup the configuration options in the Storage config.

npm install waterline-elasticsearch --save

then add to package.json

"storage": { "adapters": { ... "searcher": "waterline-elasticsearch" }, "connections": { ... "searcher: { "adapter": "searcher", "host": ":9200", "log": "warning", "index": "searcher" } } }

Register model

Now that the correct Storage adapters are configured, you'll need to tell Searcher which models you want to enable search using the searchable method. Searchable accepts an identity for a model which has already been registered.

app.get('searcher').searchable('user')

By default, Searcher will look for a field named title or name to use as the search field. You can specify different, or multiple fields to search by specifying a second options parameter, with the fields key:

app.get('searcher').searchable('user', {fields: 'firstName'}) app.get('searcher').searchable('user', {fields: ['firstName', 'lastName']})

Routes

Based on the model identify, Searcher will create the following routes

/users/search

which accepts a search parameter q. So to search for the term 'pizza':

/users/search?q=mike

The search wil return a list of results using the views below.

Views

You can provide search specific views to be used for search results:

  1. search-user-list: the list view for returned search results.
  2. search-user-detail: the detail view for an individual search result.

Alternatively, if no search templates are found, searcher will automatically use the @nxus/base-ui views for any model that is searchable (if they exist).

  1. view-user-list: the list view used to display search results.
  2. view-user-detail: the detail view linked to from the list view.

Finally, searcher will use default list/detail views if no other templates are found.
