Full-text Search – What’s New in SPS 09? CDS Full-text Index
Define a full-text index in a CDS (Core Data Services) documents by using new CDS annotations.
The "SearchIndex" annotations of a CDS element are similar to the parameters used in a SQL CREATE FULLTEXT INDEX statement and include settings to control
•Full-text indexing , e.g. define the name of the full-text index
•Fuzzy indexing, e.g. to speed up fuzzy searches on special data like postcodes and housenumbers
•Text analysis, e.g. define language detection behavior and dictionaries and rules used to process the data
Full-text index is now fully transportable in a system landscape.
@Catalog.tableType: #COLUMN
entity myTable {
key ID : Integer NOT NULL;
@SearchIndex.text: { enabled: true, storeOriginalContent: true, async: true}
TITLE : String(5000);
@SearchIndex.text : { enabled: true, async: true, textAnalysis : { mode: #EXTENDED, languageDetection: ['en'], configurationID : 'package::myconfig.hdbtextconfig' } }
ABSTRACT : LargeString;
CATEGORY : String(100);
};

Full-text Search – What’s New in SPS 09? CDS Search View
CDS annotations are provided to define search models and advanced functions which are available when querying a search model via ODATA.
The "Search" and "EnterpriseSearch" annotations of a CDS view element are similar to the search properties available in Attribute Views and include settings to define
•Columns searched in by default
•Relevance ranking
•Fuzzy search
•Columns to be exposed as so-called "facets"
•Columns for which snippets and search-term highlighting are provided by default
@Search.searchable: true
define view myView as select from "myPackage::myTable" as T1 {
@EnterpriseSearch.key : true
T1.ID,
@Search.defaultSearchElement: true
@Search.ranking: #HIGH
@Search.fuzzinessThreshold : 0.8
@Search.termMappingDictionary : 'myPackage::TERMMAPPINGS'
@Search.termMappingListID : ['default']
@EnterpriseSearch.highlighted.enabled : true
T1.TITLE,
@Search.defaultSearchElement: true
@Search.ranking: #MEDIUM
@EnterpriseSearch.snippets.enabled : true
T1.ABSTRACT,
@EnterpriseSearch.usageMode: [ #AUTO_FACET ]
T1.CATEGORY
};

Full-text Search – What’s New in SPS 09? Full-text Search with ODATA
It is now possible to expose search-enabled CDS views in ODATA and execute full-text searches via ODATA.
Besides the standard ODATA parameters, two search-specific query options are available.
•"search" This option is used to define the full-text search query, using the same syntax as available in the SQL CONTAINS() predicate.
•"facets" This option is used to define if "facets" which are specified in a CDS search-able view should be included in the ODATA response.
