The GSA Ruby Gem

Quickly and easily harness GSA indexing power with one-line feeding, searching, and faceting.

gem install gsa

the default port is set to the secure port 19902

to change the port to http, set the feed extension to the following:

GSA::FEED_EXTENSION = ":19900/xmlfeed"

Set the base uri to your GSA box

GSA.base_uri = 'http://path-to-gsa-box.com/'

1.) Structure the records you wish to feed to the GSA as an array of hashes

@products = [
{ id: "1", name: "Foo", price: 12, brand: 'BazBrand' },
{ id: "2", name: "Bar", price: 15, brand: 'BazBrand' }
]

2.) Feed the records to the GSA

GSA.feed(
  records:          @products,
  searchable:       [:name, :price],
  datasource_name:  "Baz",
  datasource_uri:   "http://your-app-base-url/products",
  datasource_uid:   "id",
  delete?:          false
)

Required

:records

The records source being pushed to the GSA index

:searchable

Attributes on the record you want searched when a query is made

:datasource_name

Name of the datasource on the GSA

:datasource_uri

The URI for your records source

:datasource_uid

The unique id of the record source

Optional

:delete?

Determines whether the feed is an "add" or a "delete" feed; defaults to "false"

If the feed is successful, the feed method will return "Success".

To search, simply pass in a query:

query = "Foo"
GSA.search( query )

To extract the UIDs from the search results, use the uids method on the search results:

GSA.uids( search_results, "id" )

To filter results using GSA filters, pass in an optional 'filters' key-value pair:

# gets all search results for 'Foo' where the price is '12'
query   = "Foo"
filters = "price:12"
GSA.search( query, filters: filters)

Multiple filters can be passed in using a '.' in-between filters:

filters = "price:12.name:Foo"

Multiple key-value pairs can be passed in as optional parameters to override defaults:

GSA.search( query, filters: filters, num: 100, sort: 'relevance', output: 'xml')

You can also do an embedded request, which means that you receive the search results in HTML. By setting the proxystylesheet parameter you define which stylesheet is used to style the results. You can set this up in your GSA.

GSA.search( query, embedded: true, proxystylesheet: "default_frontend")

Required

query

The query for the search

:filters

• Maps to the GSA 'requiredfields' parameter
• Filters search results to conform to specific required attributes

• Example: 'name:Foo.price:12'

:client

• Maps to the GSA 'client' parameter

• Default value: 'default_frontend'

• Maps to GSA 'site' parameter
• Determines which collection you want to search against

• NOTE: Set this to 1 if you change the stylesheet in your GSA, this should be an environment variable so you can refresh the stylesheet without deploying new code. Setting this to 1 by default is not advised since it will slow down your application.

:emmain

• Maps to the GSA 'emmain' parameter
• Incoming query parameter identifying root path prefix to be used for links that should refresh the main page.
• Example: 'search/'

:emsingleres
