Text Analysis
An option to the full-text index (1/3)
Text analysis is defined on a
table column.
It is bound to full-text indexing –
pre-processing steps are shared.
Results are stored in a table.
During pre-processing, a full-text index is created which is ‘attached’
as a shadow column to the indexed table column. This index can be
accessed only indirectly, when a full-text search is performed.
In contrast, the results of text analysis are stored in the table
$TA_<index_name>
.
