Remove hardcoded search result limit of 5

The search API call had a hardcoded limit=5 parameter which restricted
search results to only 5 items regardless of how many matches exist.
Removing this limit allows the server's default pagination to apply,
showing all relevant search results to the user.

Fixes #1872
