If the fuzzySimilarity is lower than 0.77, the token scoring will be part of the result score. If the fuzzySimilarity is higher than 0.77, the token scoring will not be considered, so the total scoring will be lower.

Such applications provide real-time information access and faceted search features for huge volumes of structured and unstructured text data. The toolkit enables a freestyle search of a SAP HANA attribute view, displaying and analyzing the result set. The toolkit provides UI elements (widgets) such as a search box, a result list with a detailed view, and charts for basic analytics on the result set. The widgets are interconnected and adapt in real-time to user entries and mouse-over (hover) selections. The toolkit is based on HTML5 and JavaScript libraries such as JQuery/JQueryUI, d3 (Data Driven Documents), and Tempo. The widgets use the SAP HANA Info Access HTTP service. You do not need an additional layer to run the UI; SAP HANA and a Web browser are sufficient. The toolkit is tested on Mozilla Firefox 17. It also runs on Microsoft Internet Explorer 9 in standard mode and Google Chrome. Along with the actual toolkit (the widgets), we deliver a fully operational demo Web app built using this toolkit. The demo app enables you to explore a search application dealing with a set of sample data for electronic products. You can use the demo app as a template or for reference when you start developing your own app. You can, for example, use the demo site to easily connect your own data and compose your Web site. To create a search application this way, it is sufficient to have experience in HTML and to have read this documentation. For 308 P U B L I C © 2012 SAP AG. All rights reserved.

advanced customizing and layout of the site, more in-depth knowledge of CSS and the above-mentioned JavaScript libraries is required. What is the SAP HANA Info Access HTTP Service? In the first place, SAP HANA is a database. It stores any type of raw data in its tables: master data, transactional data, numbers, texts, and so on. But SAP HANA can do more than a classic database. SAP HANA also enables you to turn raw data into meaningful information. For the world of numbers, there are the analytics features of SAP HANA. By joining, aggregating, and calculating, they can turn raw facts and numbers into meaningful measures and key figures. For the world of texts, there are the full text search and text analysis features of SAP HANA. By tokenizing, stemming, normalizing, and analyzing semantically, they can turn a set of strings into a structured and searchable text corpus. So there is meaningful information in SAP HANA. But it is still not instantly available to business end users. SQL is a very powerful tool for accessing and processing SAP HANA information. However, it operates on a very technical level deep down in the stack and far from an end user UI. This is where the info access service of SAP HANA steps in. As long as you only need read-access, meaning search or basic analytics, the service provides shortcuts to Web and mobile UIs. SAP HANA Info Access Architecture The SAP HANA info access HTTP service wraps search and analytic SQL queries and exposes them through an HTTP interface. On the UI layer, Info Access offers the HTML5 development kit including UI widgets and Web site templates. No intermediate layer is required. To provide Info Access apps to your users, you only need SAP HANA and a Web browser. 11.3.2 Installing the Service and the Toolkit The UI toolkit and the service are part of the default SAP HANA shipment, but they are not installed automatically. They are shipped as separate delivery units that you can import and activate quickly as described below.
