Abstract
A full-text search index for a table stored in a set of partitions of a database is refreshed. At a first point in time, table row distribution information and a table partitioning list are captured. At a second point in time, it is determined that an index refresh operation is to be performed. The captured table row distribution information is compared with current table row distribution information to determine whether there is at least one difference. In response to the determining that there is at least one difference, a text index distribution is re-aligned for any table rows that are affected by the change in table data row distribution by: generating a new table partitioning list, and indexing documents associated with table data rows that moved from one partition in the captured table partitioning list to another partition in the new table partitioning list.
