For English and French, you can index document theme information. A document theme is a main document concept. Themes can be queried with the ABOUT operator.You can index theme information in other languages pr
“Not quite,” assures John. Creating an index on a whim is not smart. Therefore, the Automatic Indexing feature creates the index as invisible—it is not known to the database optimizer. He explains the concept of an invisible index to the audience with a simple demonstration. He creates ...
The inverted index is light-weight, and the overall storage requirement for both reduced column and index is less than 135%, whereas existing DBMS technologies can require 200-400%. As a proof-of-concept, we evaluate univariate range queries that additionally return column values, a critical ...
Differentiate between the need for indexing the web site pages and the need for indexing databases / document collections (text, bibliographic, DBMS, etc.) Support for the concept of a "record" by the search engine. Support for structured fields and metadata Cost Choosing the right search...
the database concept of an index must be used: a duplicate of parts of the underlying information (in this case, the file data) arranged in a data structure in a different manner designed to optimize access via a particular method (in this case, resolution of a pathname in a hierarchical...
In order to save the time involved in browsing the data from the beginning, the concept of a bookmark may be used. A conventional bookmark marks a document such as a static web page for later retrieval by saving a link (address) to the document. For example, Internet browsers support a...

All the vectors clustered around it, including vectors 24 and 26, may represent a common concept. For example, the vector 28 represents a central concept "vehicles" related to all documents clustered around vectors 24 and 26. A document vector is represented by an ordered set of real numbers...
In the dataflow concept, each execution step, as implemented by a MOP and its accompanying UOP program, can apply symmetrically and independently to a prescribed tuple of input data to produce some tuple of result. Given the independence and symmetry, any number of these tuples may then be co...
the data is typically partitioned into multiple chunks. Note that “content-dependent” generally refers to the concept that edits or offsets added to a file only make local changes to the generated chunks, e.g., because the Rabin fingerprint is generated from the content itself, (and not ...
