If you use relational wildcard queries on text columns, you may get unexpected results. The following example demonstrates this using a document with a custom property value:
If you then query for this custom property value with wildcards at different positions in the string using a query page, at some positions, the wildcard query returns an empty result; however, in other positions, the resultset includes the document. For example, a relational wildcard query on the following does not return the document:
However, a wildcard query on the following does return the document:

To work around this problem, do the following:
For these types of pattern matching queries, use regular expressions instead of the relational queries. To do this, use the following syntax:
When you use regular expressions, Microsoft recommends setting AllowEnumeration to TRUE. Please note that this may cause a performance penalty on your queries.
For information on how to set AllowEnumaration, please refer to your Index Server and Site Server documentation.
- Configure only the Neutral language resources. By default, properties are indexed with English resources. If you use Neutral resources, the advanced normalization behaves differently to the other language resources. As a result, the relational wildcard query returns the expected result.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
