This type of fragmentations results in performance degradation, as it will take more time and consume more resources in jumping between the scattered data pages in order to retrieve the requested data from the underlying disk drive. External fragmentation can be caused by random delete operations that leave a number of the extent pages empty while having the extent itself reserved. The External Fragmentation is caused when the data pages of the SQL Server index are scattered on the database physical file, due to having the logical order of the SQL Server index does not match the physical order on the underlying disk drive.
This type of operations leaves the data pages unfilled and results with larger SQL Server index size and slower performance due to the need to read more data pages to retrieve the requested data. Internal fragmentation can be caused also by the random delete operations that result in empty space on the data pages. In this case, the SQL Server Engine will move about 50% of the data from the current page to the new data page that is generated from the split operation, in order to keep the SQL index tree balanced.

The Internal Fragmentation is caused by the inserting a new record or updating an existing record with values that do not fit in the current free space in the data page and result with splitting the page into two pages to fit the new value. There are two main types of SQL index fragmentation Internal and External Fragmentation. As these changes should be replicated to the related table indexes, the table index will become fragmented over time. These changes that are performed on the database table include adding new records, modifying or deleting the existing records. But these transactional tables are not static and changing very frequently over time.
On the other hand, SOSL is a programmatic way of performing a text-based search against the search index. The LWC can be used in both Lightning App Builder and Experience Cloud.
