When using the Shift+Enter line break function in Confluence, the two words are indexed as if there is no whitespace between them and they are treated as one word by the indexer.

An example of this behaviour can be seen below:

Username: 123456
Password: abcdefg

The above content would result with the indexer seeing the strings '123456' and 'Password:', which have been separated by a Line Feed, (Shift+Enter), as one continuous string '123456Password:'.

Please see further illustration of this bug in the attached screenshots.

Workaround: Anyone impacted by this issue should add a space before using the Line Feed, (Shift+Enter), line break as this will ensure that the two strings are not seen as linked by the indexer
