Steps to reproduce:

• Go to Monitoring->Maps
• Observe already created "Local network" map or create new one with >=2 words in name and >=2 or more spaces between words
• Add two spaces in "Name" input field and search for results

Result: Spaces are trimmed, all maps are visible.
Please see video attachment:

Expected: Only maps with two spaces in name should be filtered.

Same behavior appears in release/6.0 for Maintenance, Actions (trigger, discovery, autoregistration, internal, service), Host groups, Templates
name filtering.
