Steps to reproduce:
1. Create CT with ezemail field
2. Go to Content/content structure
3. Create a few CT (from 1.) with different names but same domain (ie. asdf@ez.no, zxcv@ez.no)
4. Search for CT with whole email name

Actual result:
Legacy (ezp-32124.png):
In this example 'ez' from email domain causes 'eZ Platform' folder to be also returned as value.

Solr (ezp-32124_solr.png):
All email values with same domain are displayed, uppercase letters change nothing.

Expected result:
Only the exact searched value is displayed
