text search is wonky

[Jean Jordaan]

This search:

https://bugs.launchpad.net/collective.buildout/+bugs?field.searchtext=filestorage&orderby=-importance&search=Search&assignee_option=any&field.assignee=&field.bug_reporter=&field.bug_supervisor=&field.bug_commenter=&field.subscriber=&field.omit_dupes.used=&field.omit_dupes=on&field.has_patch.used=&field.has_cve.used=&field.tag=&field.tags_combinator=ANY

returns "No results for search filestorage", although this issue:

https://bugs.launchpad.net/collective.buildout/+bug/287543

contains the string 'filestorage' many times. A search for 'storage' does work.
