Search as a Service
Choice ALGOLIA
The Algolia model provides search as a service, offering web search across a client’s website using an externally hosted search engine.
Although in-site search has long been available from general web search providers such as Google, this is typically done as a subset of general web searching. The search engine crawls or spiders the web at large, including the client site, and then offers search features restricted to only that target site. This is a large and complex task, available only to large organisations at the scale of Google or Microsoft.
Algolia’s product only indexes their clients’ sites and so the search task is far simpler. Data for the client site is pushed from the client to Algolia via a RESTful JSON API, then the search box is added simply to the client’s web pages. This search model is intended to give the performance and sophistication advantages of a full in-house search engine operating on the native web site back-end database, but with the simplicity of setup of using a site-restricted Google search.
Algolia claim a number of advantages for their approach, including speed of response from searching a single site rather than the entire web Moreover, as Algolia’s search can be tailored to the client site, its known structure and its metadata facets, the search offered can be smarter and more site-specific than a generalised web text search. This improves the relevance of search results as searching may take the semantics of site content into account. A web site selling both puppies and dog clutches could avoid the search confusions and homonymy that bedevil the simple text-based search approaches.
