Pagination start does not reset to 0 when the user does a new search

[jrobbins]

Describe the bug
Pagination does not reset when doing a new search, which can give the user the message that there are no results when there are < 100.

To Reproduce
Steps to reproduce the behavior:

1. Go to the new search page
2. Navigate to a higher pagination page
3. Do a query for something that has < 100 results.
4. See "No results" because the user has start=100 or more.

Expected behavior

1. start parameter should reset to 0 on a new search.
2. there should be a better error message when there are N results but start > N.
