Enterprise search is used in a wide variety of applications and solutions. this means it has to be highly flexible, allwing you to tune it in multiple directions because what is important to one application may not be important to another.
Embedded Search
Search is becoming a common requirement for many applications. In some applications search is a critical aspect of the solution. For example, legal discovery applications (e-discovery) use embedded search technologies to search through a massive volume of
e-mails and documents to obtain critical evidence in a legal investigation. Other examples are in compliance monitoring, enterprise content management (ECM), e-mail archiving, supply chain systems, customer management, etc.
The unique requirement for embedded search are high flexibility, a small footprint, the ability to scale incrementally, and the ease of integration and use.
Intranet Search
Intranet search refers to searching sources of content internal to the enterprise such as shared file directories, e-mail systems, and internal web sites and wikis, and the case of newer search solutions, databases. Search technology is used for improving productivity or helping employees locate specific information they need as part of their daily jobs.
There is an infinite array of intranet implementations that are highly specialized, solving one problem or another in the enterprise, for example e-mail surveillance, privacy auditing, content management, etc.
The key requirements for intranet search are breadth and depth on handling various document formats, ease of integration with enterprise systems and information repositories, enhanced user interface (such as navigated search or facets), and a security model for handling user authorization based on enterprise credentials. Some of the more specialized intranet applications also require enhanced features such as entity extraction, document clustering, text mining, and high performance with horizontal scalability.
Web Portals
Search is an essential element of every consumer facing portal where fast and accurate access to information is the sole purpose of the application. Online catalogs for retailers, job searching sites, government portals, and commercial information portals for researchers, marketers, and business managers all use search technology to increase revenue and self service. The new revenue can come from either new customers paying subscriptions or keeping browsers around longer at a site that monetizes through online advertising.
The key requirement for web portals are an enhanced user interface (such as navigated search), the ability to easily manage and control search results with relevance tuning, high performance (sometimes with thousands of concurrent users), and incremental scalability with 24/7 availability.
Search in Analytics
Data mining applications are becoming a must have component in the corporate business intelligence (BI) stack. But not all business content is nicely organized in relational databases or even resides in enterprise systems. E-mails, free text fields in customer surveys, voice recordings from customer service centers, online news, and competitors' web sites all contain important information about the business. In these applications, enterprise search can be sued to bring together the content, extract concepts, perform sentiment analysis, or find new relationships in the data to improve data analysis.
