Full-text searching in ODATA


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.


Full-text Search – What’s New in SPS 09? SAP HANA InA File Loader

The SAP HANA InA File Loader component has been improved.

• Support of SSL, HTTP proxies and HTTP authentication through HTTP destinations

• Administration UI

• Enhanced monitoring functions

• Simplified security setup and maintenance


Full-text Search – What’s New in SPS 09? Additional Enhancements

New monitoring function for the full-text indexing process.

SELECT INDEXING_STATUS("myColumn") FROM "myTable"; information on indexing status per document

SELECT INDEXING_ERROR_CODE("myColumn"), INDEXING_ERROR_MESSAGE("myColumn") FROM "myTable"; information on indexing errors per document

A plain text representation of binary file formats can be retrieved via SQL.

SELECT PLAINTEXT("myBinaryContent") FROM "myTable";
