Lucene Index Provider does not correctly handle Like constraints containing an Ampersand with a leading or trailing space

The Lucene index provider fails to find nodes that match the following LIKE constraints:

• LIKE '% &%'
• LIKE '%& %'

If there is no space it works correctly

• LIKE '%&%'

or if there is no & it works correctly

• LIKE '% %'

If the index is disabled then the query works as expected.
