Error on searching names containing parenthesis

[LibrErli]

if you are searching for an entity where its preferred name contains parenthesis - (i think there was already an issue about it) - the search request fails, if the parenthesis aren't closed.

• Searching for Olbendorf (Politischer Bezirk Güssing) succeed
• Searching for Olbendorf (Politischer Bezirk Güssing failed

Adding to this: having parenthesises within a name results in having no results:

• Searching for Re(c)hlinger, Johannes has no results
• Searching for Rehlinger, Johannes is successfull
