Describe the bug
When a search of Janeway begins with a blank space, the resulting hit count is unexpectedly high, seemingly almost everything published.

Janeway version
1.5.1 RC1 (Repository confirmed, possibly journals also)

To Reproduce
Steps to reproduce the behavior:

1. Search Janeway for a published article title, starting the search with a space. Note the hit count. For example, this search of EarthArXiv for "High-resolution methane mapping with the EnMAP" begins with a space and results in 3933 hits: https://eartharxiv.org/repository/search/%20High-resolution%20methane%20mapping%20with%20the%20EnMAP/(at the time, there were 4335 items published)
2. Compare remove the starting space and compare. For example, this search results in 3933 hits: https://eartharxiv.org/repository/search/High-resolution%20methane%20mapping%20with%20the%20EnMAP/ (note: adding a trailing space at the end does not change the result count.)

Expected behavior
The initial space would be ignored.
